    Technical Field
    The present invention relates to a hybrid cable used for crane drive cables, cables for anchoring ships, and other applications, and to a method for making such a hybrid cable. Technical Basics
    Wire cables are used in the form of drive cables and anchor cables. Fig. 7 shows a typically conventional steel wire rope used as a driving cable and anchoring cable. The steel wire cable 50 includes an IWRC 51 (Independent Wire Cable Core) disposed in the center of it and six steel side wires 52 layered around the IWRC 51. The IWRC 51 is being formed by the accommodation of seven steel wires 53.
    US patent document No. 4887422 describes a hybrid cable that does not include an IWRC 51, but a fiber cable arranged in its central part and multiple steel wires layered around the fiber cable. Fiber cables are lighter than IWRCs and therefore the hybrid cable is lighter than steel wire cables.
    In general, in fiber cables, the rate of tensile strength of a fiber cable due to the tensile strength of a filament (a single fiber or a line element) included in the fiber cable (efficiency of use of resistance) is low . That is, the tensile strength of a fiber cable formed by the deposition of many fiber filaments is lower than the tensile strength of one of the fiber filaments. For this reason, not using an IWRC but using a fiber cable may result in the tensile strength not becoming the same as for steel wire cables of the same diameter including the presence of a IWRC. Summary of the Invention
    An objective of the present invention is to provide a hybrid cable exhibiting a tensile strength equal to or higher than that for steel wire cables that will include an IWRC.
    Another objective of the present invention is to provide a hybrid cable that will not cause direct damage to a fiber cable.
    The present invention is directed to a hybrid cable including a high-strength synthetic fiber core and multiple side wires, each of which has been formed by the deposition of multiple wires there and seated near the outer periphery of the synthetic fiber core. high strength, where the high strength synthetic fiber core consists of a high strength synthetic fiber cable formed by the interleaving of multiple high strength synthetic fiber bundles where given the interlacing step of the high synthetic fiber bundles resistance is represented by "L" and the diameter of the high-strength synthetic fiber cable is represented by "d", with the L / d value equal to or greater than 6.7.
    The high strength synthetic fiber cable is formed by the interweaving of multiple bundles of high strength synthetic fiber. The bundles of high-strength synthetic fiber each come from the grouping of multiple strands of high-strength synthetic fiber, such as aramid fibers, ultra-high molecular weight polyethylene fibers, polyarylate fibers, PBO fibers, or carbon fibers. In the present invention, the high strength synthetic fiber cable comes to be formed through the use of fiber filaments having a tensile strength of 20 g / d or greater (259 kg / mm2). When a tensile force is applied to the hybrid cable, the high-strength synthetic fiber cable, formed in turn from the interweaving of multiple high-strength synthetic fiber bundles, contracts slightly (radially) inward. Due to the fact that the contraction was caused by a uniform force, the shape of the high-strength synthetic fiber cable, that is, the circular shape of the cross section can be maintained to show a high shape preservation effect.
    The multiple side wires are deposited near the outer periphery of the high-strength synthetic fiber cable. The side wires are each formed by the deposition of multiple steel wires. The multiple side wires can be deposited near the outer periphery of the high-strength synthetic fiber cable in an ordinary deposition or in a Lang layer. The number of high strength synthetic fiber filaments forming each fiber bundle and the number of high strength synthetic fiber bundles forming the high strength synthetic fiber cable comes to be defined according, for example, to the diameter required for the hybrid cable.
    The high strength synthetic fiber cable has a lower weight and elastic coefficient and therefore has a higher fatigue resistance than steel wire cable cores (ie IWRCs) of the same diameter. That is, the high-strength synthetic fiber cable is light, easy to bend, and less prone to fatigue due to repetitive applications from tension and bending. The hybrid cable employing such a high strength synthetic fiber cable is also lightweight and offers high durability and flexibility.
    In general, the tensile strength of fiber cables including high-strength synthetic fiber cables varies depending on the deposition angle (angle of inclination with respect to the cable axis) of the fiber bundles forming the fiber cable. The lower the deposition angle of the fiber bundles, the higher the tensile strength of the fiber cable, while the greater the deposition angle of the fiber bundles, the lower the tensile strength of the fiber cable. The deposition angle of the fiber bundles is proportional to the deposition or entanglement step of the fiber bundles and inversely proportional to the diameter of the fiber cable.
    The hybrid cable, according to the present invention, comes to be characterized in the sense that the step of interlacing the high strength synthetic fiber bundles constituting the high resistance synthetic fiber cable provided near the center of the hybrid cable is represented by "L", and the diameter of the high strength synthetic fiber cable is represented by "d", with the L / d value being equal to or greater than 6.7. Since the diameter "d" of the high strength synthetic fiber cable is defined according, for example, to the diameter of the hybrid cable to be made available as a final product, the L / d value is generally adjusted by "L" interlacing step of high-strength synthetic fiber bundles.
    The longer the "L" interlacing step of the high-strength synthetic fiber bundles, that is, the higher the L / d value, the smaller the deposition angle of the high-resistance synthetic fiber bundles, and therefore the greater the makes the tensile strength of high-strength synthetic fiber cable. That is, the interleaving of multiple bundles of high strength synthetic fiber in a long "L" interlacing step may result in a high strength synthetic fiber cable containing a high tensile strength and therefore resulting in a cable hybrid featuring high tensile strength including high strength synthetic fiber cable.
    Through tensorial tests it was confirmed that the high strength synthetic fiber cable formed through the interleaving of multiple bundles of high resistance synthetic fiber, so that the L / d value will be equal to or greater than 6.7 offers a tensile strength equal to or higher than that for steel wire cables (ie IWRCS) of the same diameter formed by the deposition of multiple steel wires. The hybrid cable coming in accordance with the present invention featuring a high strength synthetic fiber cable formed from the interweaving of multiple bundles of high strength synthetic fiber, so that the L / d value is equal to or greater than 6, 7 offers a tensile strength equal to or greater than that for steel wire cables (see Fig. 7) of the same diameter, and, in addition, has become lighter and offers high durability and flexibility, as mentioned earlier .
    There is also confirmation through a tensile test that if the L / d value is equal to or greater than 6.7, the tensile strength ratio of the high strength synthetic fiber cable due to the tensile strength of the filament high strength synthetic fiber (efficiency of use of resistance) is 50% or more. The present invention can increase the efficiency of employing the strength of the high strength synthetic fiber cable and, consequently, the tensile strength of the hybrid cable.
    The higher the L / d value (that is, the longer the "L" interlacing step of the high-strength synthetic fiber bundles), the higher the tensile strength of the synthetic fiber cable becomes. high strength, as mentioned earlier, while on the contrary, the lower the degree of elongation (elongation occurring before breaking) of the high strength synthetic fiber cable, if the degree of elongation of the high resistance synthetic fiber cable inside the hybrid cable it will be less than the degree of elongation of the lateral steel wires positioned in the outer part of the hybrid cable, only the high strength synthetic fiber cable can break inside the hybrid cable during use To address this problem, the degree of elongation of the high strength synthetic fiber cable is preferably equal to or higher than the degree of elongation of the side wires.
    The degree of elongation of the high-strength synthetic fiber cable also depends on the L / d value. Highly resistant synthetic fiber cable containing a lower L / d value (ie, presenting a shorter "L" interlacing pass) structurally exhibits a higher degree of longitudinal elongation, whereas high-fiber synthetic cables strength showing a higher L / d value (ie, presenting a larger "L" interlacing step) structurally exhibit a lower degree of longitudinal elongation. Therefore, the degree of elongation of the high strength synthetic fiber cable can still be adjusted by the interlacing step "L" of the high strength synthetic fiber bundles.
    The L / d value is limited, preferably, to be equal to or less than 13. It is verified through a tensile test that the high resistance synthetic fiber cable, in case the L / d value comes to being less than or equal to 13, exhibits an elongation of 4% or more. The degree of elongation of the side steel wires used in hybrid cables is, in general, from 3 to 4%. If the L / d value is 13 as mentioned above, the high-strength synthetic fiber cable exhibits a 4% elongation, approximately identical to the degree of elongation of the side wires. If the L / d value is less than 13, the degree of elongation of the high strength synthetic fiber cable becomes more than the degree of elongation of the side wires. This may reduce the possibility that only the high strength synthetic fiber cable can break inside the hybrid cable when using the hybrid cable. It should be understood that the L / d value may be even lower (that is, limited to be equal to or less than 10) for an additional reduction as to the possibility that only high-strength synthetic fiber cable can come breaking inside the hybrid cable when using the hybrid cable.
    In one type of implementation, the high-strength synthetic fiber core also comprises an interlaced bearing formed by bundles of high-strength synthetic fiber, each of which is composed of multiple fiber filaments and covering the outer periphery of the cable. high strength synthetic fiber. Each bundle of fiber included in the interlaced bearing is formed by bundling many synthetic fibers (high-strength synthetic fibers or standard synthetic fibers) or natural fiber filaments. The interlaced bearing is formed in a cross-sectional manner near the outer periphery of the high-strength synthetic fiber cable. When a tensile force is applied to the hybrid cable, the interlaced bearing contracts inwards (radially) and compresses close to the outer periphery of the high-strength synthetic fiber cable with a uniform force. In this way, the shape of the high-strength synthetic fiber cable, that is, the circular shape of the cross section, can still be preserved by the interlaced bearing for the prevention of local deformation (loss of shape) of the high-resistance synthetic fiber cable and therefore, the deterioration of the tensile strength. In addition, the interlaced bearing can prevent the high-strength synthetic fiber cable from stretching or being damaged.
    In another type of implementation, the high-strength synthetic fiber core also comprises a layer of resin covering the outer periphery of the interlaced bearing. The outer periphery of the interlaced bearing is covered with, for example, a layer of synthetic plastic resin. The resin layer can absorb or reduce the impact forces, should they be applied, for further prevention of deformation or damage of the high strength synthetic fiber cable.
    The resin layer preferably has a thickness of 0.2 mm or more. The resin layer, if very thin, may break. In the case of a thickness of 0.2 mm or more, the impact forces applied to the high-strength synthetic fiber cable provided near the center of the hybrid cable can be sufficiently absorbed or reduced.
    If the resin layer is too thick, while the diameter of the hybrid cable is specified as the final product, the high strength synthetic fiber cable is inevitably driven to have a relatively small diameter. The cross-sectional area of the resin layer accounts for, preferably, less than 30% of the cross-sectional area of the high-strength synthetic fiber cable, which consists of three layers: the high-strength synthetic fiber cable, the interlaced bearing , and the resin layer. That is, given that the cross-sectional area of the resin layer is represented by D1 and the cross-sectional area of the high-strength synthetic fiber cable is represented by D2, the value of D1 / D2 is less than 0, 3. In the form of a final product, the hybrid cable can offer a predetermined tensile strength because the high-strength synthetic fiber cable takes into account a higher percentage of the high-strength synthetic fiber cable.
    A highly resistant synthetic fiber cable can be positioned not only in the central part of the hybrid cable, but also in the center of each of the multiple side wires in the outer part of the hybrid cable. In a type of implementation, a high-strength synthetic fiber cable can be positioned near the center of each of the multiple side wires. This gives the condition that the hybrid cable can have a lower weight and also a greater resistance to fatigue. It should be understood that the high-strength synthetic fiber cable positioned in the center of each side wire can also be covered with a layer of resin. In addition, such a type of interlaced bearing, as mentioned above, can be formed between the outer periphery of the high-strength synthetic fiber cable positioned close to the center of each side wire and the resin layer.
    In addition, in each of the multiple side wires, the cross-sectional area of the resin layer preferably accounts for less than 30% of the cross-sectional area of the three layers: high-strength synthetic fiber cable, interlaced bearing, and resin layer. That is, given that the cross-sectional area of the resin layer is represented by D3, the cross-sectional area of the high-strength synthetic fiber cable is represented by D4, and the cross-sectional area of the interlaced bearing is represented by D5. in each of the multiple side wires, the value D3 / (D3 + D4 + D5) is less than 0.3.
    In one type of implementation, the side wires are prepared in a Seale format. In comparison to the Warrington shape, the inner peripheral portion in the Seale shape has a cross section closer to that of a circle. The circular shape of the cross section of the high-strength synthetic fiber cable positioned near the center of each side wire can be preserved to prevent deformation (loss of shape) of the cable and, therefore, the deterioration of the tensile strength.
    The present invention is further directed to a method for the manufacture of such a hybrid cable as mentioned above, where multiple lateral wires, each of which are formed by the deposition of multiple steel wires are seated on the outer periphery of a cable of high strength synthetic fiber formed by the interleaving of multiple high strength synthetic fiber bundles, each of which is composed of multiple high strength synthetic fiber filaments, where the "L" interlacing step of the high strength synthetic fiber bundles is adjusted in such a way that the tensile strength of the high strength synthetic fiber cable is equal to or greater than the tensile strength of a steel wire cable with the same diameter and the degree of elongation of the fiber cable high-strength synthetic material is equal to or higher than the degree of elongation of the side threads.

    Fig. 1 consists of a cross-sectional view of a hybrid cable coming in accordance with a first embodiment. Fig. 2 consists of the hybrid cable shown in Fig. 1, with a fiber cable, an interlaced bearing, and a layer of resin included in a core near the center of the hybrid cable being partially exposed. For purposes of illustrative convenience, the scale rate differs between Figures 1 and 2.
    The hybrid cable 1 includes a high-strength synthetic fiber core 2, called the Super Fiber Core (hereinafter referred to as SFC 2) containing high-strength synthetic aramid fibers and six designed steel side wires 6 deposited around the SFC 2. SFC 2 is positioned in cross section near the central part of hybrid cable 1. Both hybrid cable 1 and SFC 2 have approximately the shape of the circular cross section.
    The SFC 2 includes a high-strength synthetic fiber cable 3 positioned in the central part of it, being wrapped by the interlaced bearing 4. The outer periphery of the interlaced bearing 4 is still covered with a layer of resin 5.
    The high-strength synthetic fiber cable 3 is formed by preparing multiple sets of two bundles of multiple high-strength aramid fiber strands 31 (hereinafter referred to as high-strength synthetic fiber bundles 30), making the entanglement of the multiple high-strength synthetic fiber bundles 30. Since the interleaving step of the high-resistance synthetic fiber bundles 30 (length for winding the high-strength synthetic fiber bundles 30) is represented by "L" , and the diameter of the high-strength synthetic fiber cable 3 is represented by "d", the L / d value is within the range of 6.7 s L / d <13. Fig. 2 presents a situation where the L / d value is approximately 7.0. The technical meaning of limiting the L / d value limited to a range has its description given in detail below.
    The high strength synthetic fiber cable 3 has a lower weight and elastic coefficient and, therefore, a higher fatigue resistance than that for the steel wire cable cores (ie IWRCs) (see Fig. 7 ) of the same diameter. The hybrid cable 1 employing such a high-strength synthetic fiber cable 3 is still light, offering high flexibility and durability. In addition, the high-strength synthetic fiber cable 3, which is formed by the interleaving of multiple high-strength synthetic fiber bundles 30, structurally exhibits a longitudinal elongation and, when subjected to the application of a tractive force, comes to contract ( radially) inward with uniform force. Therefore, the shape of the high-strength synthetic fiber cable 3, that is, the circular shape of the cross section, has a tendency to be maintained during the use of the hybrid cable 1.
    The interlaced bearing 4 is formed by the interleaving of multiple bundles of polyester fiber 40 around the outer periphery of the high strength synthetic fiber cable 3. Each bundle of polyester fiber 40 is formed by bundling multiple filaments of polyester fiber 41. The interlaced bearing 4 is formed in a cross section in an approximately circular shape along the outer periphery of the high-strength synthetic fiber cable 3. The interlaced bearing 4 can prevent stretching, damage, or rupture of the high strength synthetic fiber cable 3.
    The total length of the outer periphery of the high-strength synthetic fiber cable 3 is encased by the interlaced bearing 4. The interlaced bearing 4 that is formed by the bundles of interwoven polyester fiber 40 contracts inwards (radially) when the application of a tensile force, compressing close to the outer periphery of the high-strength synthetic fiber cable 3 by means of a uniform force. Therefore, the shape of the high strength synthetic fiber cable 3 is prone to be preserved also by the interlaced bearing 4 when using hybrid cable 1. This may prevent the high resistance synthetic fiber cable 3 from becoming deform locally where a rupture could probably originate.
    The total length of the outer periphery of the interlaced bearing 4 is covered with a layer of polypropylene resin 5. The resin layer 5 is plastic in order to prevent the high-strength synthetic fiber cable 3 from being stretched and absorbed. or by reducing the impact forces, if they can be applied, preventing damage, breakage or deformation of the high resistance synthetic fiber cable 3. The resin layer 5 has a thickness of 0, 2 mm or more so as not to break when using hybrid cable 1. It should be understood that the resin layer 5 does not need to be unnecessarily thick, having a cross-sectional area for it preferably less than 30% of the cross-sectional area of the SFC 2.
    The six side wires 6 are deposited around the outer periphery of the SFC 2, which has a three-layer structure consisting of the high-strength synthetic fiber cable 3, the interlaced bearing 4, and the resin layer 5. Each side wire 6 is formed by the deposition of 41 steel wires in the Warrington format (6 x WS (41)). In addition, each side wire 6 can be deposited in an ordinary layer or Lang layer.
    Fig. 3A shows the result of a tensile test for the efficiency of the use of resistance (resistance utilization rate) of the high-resistance synthetic fiber cable 3. Fig. 3B shows graphically the result of the tensile test of Fig 3A, where the vertical axis represents the efficiency of using resistance (5), while the horizontal axis represents the L / d value. Fig. 3B shows the multiple graphs based on the result of the tensile test in Fig. 3A and an approximate curve obtained from these graphs.
    From the tensile test, it was found that the multiple high-strength synthetic fiber cables 3 (nine in this example) were prepared with a constant diameter "d" (9.8 mm) and their respective different interlacing steps "L" , being cut to a predetermined length. One end of each high-strength synthetic fiber cable 3 is cut to a predetermined fixed length, at the request of its other end. The tensile load was gradually increased and recorded (in the form of a rupture load) when the high strength synthetic fiber cable was broken 3. The rupture load record was then divided by the denier value of the cable. high strength synthetic fiber 3 for obtaining the tensile strength of high strength synthetic fiber cable 3 (unit: g / d). The high strength synthetic fiber cable 3 for the tensile test was prepared using high strength synthetic fiber filaments 31 with 1500 denier and a tensile strength of 28 g / d. The tensile strength (28 g / d) of the high strength synthetic fiber filament 31 was then divided by the tensile strength of each high strength synthetic fiber cable 3 obtained in the tensile test and multiplied by 100 to obtain an efficiency of use of resistance (unit:%). The strength-using efficiency of each high-strength synthetic fiber cable 3 represents how efficiently the high-strength synthetic fiber cable 3 makes use of the tensile strength of the high-strength synthetic fiber filament 31.
    Referring to Fig. 3A, the tensile strength of each high-strength synthetic fiber cable 3 is less than that of the tensile strength (28 g / d) of the high-strength synthetic fiber filament 31 included in the cable. high strength synthetic fiber
    Referring to Figures 3A and 3B, the higher the value of L / d, the more relatively high the efficiency of using resistance, while the lower the value of L / d, the lower the efficiency of using resistance. Compared to high strength synthetic fiber cables 3 having a higher L / d (ie, containing a longer elongated interlacing pitch "L" for a constant diameter "d"), high strength synthetic fiber bundles 30 included in high-strength synthetic fiber cables 3 containing a lower L / d (ie with a shorter interlacing pitch "L" for a constant diameter "d") have a greater deposition angle (inclination angle with respect to the cable axis), which leads to a weak longitudinal force being applied to the high-strength synthetic fiber filaments 31 when pushed. For this reason, high-strength synthetic fiber cables 3 having a lower L / d are considered to have a lower tensile strength and efficiency in employing strength. It is necessary to increase the value of L / d to obtain a high-strength synthetic fiber cable 3 showing tensile strength and efficiency in using higher strengths.
    It was confirmed through tensor tests that the adjustment of the value of L / d (interlacing step "L") coming to be equal to or greater than 6.7 offered a tensile strength equal to or greater than the resistance to tensile strength (around 14.0 g / d) of steel wire cables (ie IWRCs) (see Fig. 7) of the same diameter. It has also been confirmed by tensor tests that high-strength synthetic fiber cables 3 with an L / d value of 6.7 or greater have an efficiency of using strength greater than 50%. The same applies to high-strength synthetic fiber cables 3 with their respective different diameters.
    Fig. 4A shows another result from a tensile test as to the degree of elongation of the high-strength synthetic fiber cable 3. Fig. 4B graphically shows the result of the tensile test in Fig. 4A, where the vertical axis represents the degree of elongation (5), while the horizontal axis represents the value of L / d. Fig. 4B shows multiple graphs based on the result of the tensile test in Fig. 4A and an approximate curve obtained from these graphs. In addition, in reference to the degree of elongation of this tensile test, multiple (five in the example) high-strength synthetic fiber cables 3 having a constant diameter "d" (9.8 mm) and their respective different interlacing steps were prepared "L" of the high-strength synthetic fiber bundles 30. One end of each high-strength synthetic fiber cable 3 was fixed and cut to a predetermined length, while the other end of the cable was ordered. The tensile strength grew gradually and, when the high resistance synthetic fiber cable 3 broke, the degree of elongation (%) was measured with respect to the predetermined length prior to the tensile test procedure.
    As previously mentioned, the higher the L / d value, the greater the tensile strength and the efficiency of using the high-strength synthetic fiber cable 3. However, with reference to Fig. 4B, the higher the value of L / d, the lower the degree of elongation of the high-strength synthetic fiber cable 3 becomes. This is due to the fact that the high-strength synthetic fiber bundles 30 included in the high-resistance synthetic fiber cables 3 have an L Higher d / d have a lower deposition angle, resulting in structurally a small degree of elongation. If the degree of elongation of the high-strength synthetic fiber cable 3 is low, the high-resistance synthetic fiber cable 3 may break inside the hybrid cable 1 when using the hybrid cable 1 using the side wires 6. The degree of elongation of the high-strength synthetic fiber cable 3 is required to be at least equal to the degree of elongation of the side wires 6 used in the hybrid cable 1.
    The degree of elongation of the high-strength synthetic fiber cable 3 depends on the L / d value of the high-resistance synthetic fiber cable 3. The L / d value of the high-resistance synthetic fiber cable 3 is adjusted so that the degree of elongation of the high-strength synthetic fiber cable 3 will be identical to or greater than the degree of elongation of the side wires 6 used in the hybrid cable 1. For example, if the degree of elongation of the side wires 6 used in the hybrid cables is of 3%, the L / d value of the high-strength synthetic fiber cable 3 is adjusted so that its degree of elongation is 3% or greater, or preferably, with a flexibility of 4% or greater. It has been confirmed by tensor tests that a degree of elongation of 4% or greater can be achieved with an L / d value of 13 or lower. The L / d value of 13 or lower allows the high-strength synthetic fiber cable 3 to have an equal or higher degree of elongation than that of the side wires 6, which may reduce the possibility that only a break in the high-strength synthetic fiber cable 3 can occur during the use of the hybrid cable 1.
    It should be understood that the L / d value may be even lower (that is, limited to be equal to or less than 10), giving conditions for the high strength synthetic fiber cable 3 to present a reliable degree of higher elongation. . This may further reduce the possibility that the high-strength synthetic fiber cable 3 may break in front of the side wires 6.
    Fig. 5 consists of a cross-sectional view of a hybrid cable coming in accordance with a second embodiment. The hybrid cable 1A, according to the second modality, differs from the hybrid cable 1 coming according to the first modality in the sense that the SFC 2a comes to be formed not only near the central part of the hybrid cable 1 A, as well as well as near the central part of each of the six side wires 6a.
    As given for SFC 2, the SFC 2a provided near the central part of each of the six side wires 6a also has a three-layer structure consisting of a high-strength synthetic fiber cable 3a, an interlaced bearing 4a, and a resin layer 5a. Once the weight of the six side wires 6a is reduced, the integral weight of the hybrid cable 1A is further reduced. The resin layer 5a does not have to be unnecessarily thick, with its cross-sectional area, preferably accounting for less than 30% of the cross-sectional area of the SFC 2a.
    Fig. 6 consists of a cross-sectional view of a hybrid cable 1B coming in accordance with a third embodiment, differing from hybrid cable 1A (see Fig. 5) according to the second embodiment in that the side wires 6b come to be formed not in the Warrington format, but in the Seale format. In the Seale format, the side wires 6b come into contact with the SFC 2a in a more rounded and uniform way than in the Warrington format, where there is a tendency for the circular configuration of the cross section of the fiber cable to be maintained high strength synthetic 3.
    Since the circular configuration of the high-strength synthetic fiber cable 3 has the propensity to be preserved in the Seale format, it happens that in the hybrid cable 1B, according to the third modality shown in Fig. 5, the SC 2a contained inside each side wire 6b it can exclude the interlaced bearing 4a to assume a two-layer structure consisting of the high-strength synthetic fiber cable 3 and the resin layer 5a.
    Even though the hybrid cables described above 1, 1A, 1B, each include six side wires 6, 6a, 6b, the number of side wires is not restricted to six, but can reach seven to ten , for example.
