    Technical Field
    [0001] The present invention relates to a hybrid cable comprising a core element and closed metallic outer layers, for the termination of the cable and for the method of producing such a hybrid cable. Background Technique
    [0002] Conventional steel cables and cables usually feature a metallic core surrounded by an outer layer of terminals or helically positioned steel cable. Metal-core cable has a disadvantage of being extremely posed in long lengths.
    [0003] For this reason, cables with a core of natural or synthetic fibers braided together with the metallic terminals, that is, so called hybrid cables, are introduced to give various characteristics to the cables depending on the type of natural or synthetic fibers used.
    [0004] An advantage of a hybrid cable compared to an entirely steel cable is the lower weight of the cable and better performance, such as bending fatigue and tension.
    [0005] The advantage of the hybrid cable over a fully synthetic cable, eg nylon, is that the hybrid cable is highly resistant to abrasion, compression and stretching while also having the desired characteristics of hardness and excellent resistance to wear. impact.
    [0006] US-A-4 034 547 describes a composite cable 10 comprising a synthetic core 12 and a metal sheath 14 as illustrated in Figure 1. The synthetic core 12 is formed of a high fiber composite or composition. performance and sheath 14 is formed from a plurality of wires or lugs 16. This patent also discloses that an approximate weight of 30% lighter than the corresponding size weight of the wire rope can be obtained by the composite rope.
    [0007] The advantage of hybrid cables comes into effect in particular in the case of long cables for suspended use, such as suspension or drag cables in mining, cranes and elevators, aerial cables or cables for offshore installations or uses in commercial and marine fishing, and offshore mooring. This is because, during such use, the weight of the rope alone already takes up a large part of its load bearing capacity and winch load capacity; the payload is correspondingly limited. For that reason, hybrid ropes are desirable in these operations as they provide comparable performance to steel ropes and lighter weight expanding the possibilities, for example, deeper mooring in the water.
    [0008] There is a demand to also reduce the weight of hybrid cables while maintaining or desirably improving their performance. Description of the Invention
    [0009] It is a main objective of the present invention to explore a new product to adjust to market demand.
    [00010] It is another object of the present invention to devise a hybrid cable having low volume and weight compared to its strength and the method to produce the same.
    [00011] It is yet another object of the present invention to plan a hybrid cable having a resistance to rotation and a sufficient resistance to corrosion.
    [00012] It is a further aim of the present invention to apply the low weight hybrid cable according to the invention in the case of long length for suspended use.
    [00013] According to a first aspect of the present invention, at this point a hybrid cable is provided comprising a core element, a first and at least a second closed metallic layer surrounding said core element. The core element includes a grouping or composition of synthetic yarns. The closed metal first layer includes a plurality of first wire-like members helically braided together around the core element in a first direction. The second closed metallic layer includes a plurality of second wire-like members helically braided together around said core element and said first metallic layer closed in a second direction. The cross-sectional area of the core element is greater than the total cross-sectional area of the first and second closed metal layers.
    [00014] The ratio of the cross-sectional area of the core element to the total cross-sectional area of the first and second closed metal layers is preferably 70:30, and more preferably 65:35 and more preferably 60:40. The ratio of the core element to the outer metallic layers, i.e. the ratio of the synthetic wires to the metal, determines the assumed cable weight by itself. This is a large part of the cable's load-bearing capacity. Compared to a fully heavy wire rope, this hybrid rope can reduce weight by up to 40% or more. In other words, this rope having significantly reduced weight, for example, being used in platforms with mooring at sea, can be used in larger columns of water. As a reference, an all-steel cable can go up to a maximum of 1500 to 2500 m deep in water, while hybrid cable characterized by about 40% or more weight reduction can go even as deep as water. 3500 to 4000 m water depth.
    [00015] Simultaneously, it should also be noted that two closed metallic layers are employed outside the core element made of synthetic yarns. In a preferred example, the cross-sectional area ratio of the core element to the closed metal layers is around 65:35. This produces the rope to be robust while remaining a relatively high modulus of elasticity. This cannot be accomplished by simply reducing the wire diameter of the hybrid cable in the prior art as shown in Figure 1. A wire diameter reduction in the single metallic outer layer hybrid cable will make the cable less robust. More importantly, it is found in the invention, in the case of only one external metallic layer of the synthetic core, when the diameter of the metallic wires is acquiring the external metallic wires, very small, having "spring effect", which means one or more of the wires are not in their position. This bad positioning can occur under no stress or under stress. In any case, the metallic wires according to the cable structure of the present application can be well positioned due to the balance of at least the two outer metallic layers and the choice of diameter of the wire-like metallic members.
    [00016] The hybrid cable has a diameter in the range of 10 to 400 millimeters, eg 50 millimeters, 100 millimeters and 200 millimeters. The hybrid cable preferably further comprises a sheath surrounding the closed first and/or second metallic layer. The coating on the cable can comprise a thermoplastic, plastomer, braided coating and/or elastomer.
    [00017] As an example, wire-like members are steel wire and/or wire rope filaments. Cable wires can be made of high carbon steel. A high carbon steel has a steel composition as follows: a carbon content ranging from 0.5% to 1.15%, a manganese content ranging from 0.10% to 1.10%, a silicon content ranging from 0.10% to 1.30%, the sulfur and phosphorus contents being limited to 0.15%, preferably up to 0.10% or even less; additional microalloy elements such as chromium (up to 0.20% - 0.40%), copper (up to 0.20%) and vanadium (up to 0.30%) can be added. All percentages are percentages by weight.
    [00018] Preferably, the steel wires and/or the wire rope filaments of at least one metallic layer are individually coated with zinc and/or zinc alloy. Most preferably, the coating is formed on the surface of the wire rope through the galvanizing process. An aluminum zinc coating has better overall corrosion resistance than zinc. In contrast to zinc, aluminum zinc coating is more temperature resistant. Also in contrast to zinc, there is no flaking with the zinc aluminum alloy when exposed to high temperatures. An aluminum zinc coating may have an aluminum content ranging from 2% by weight to 12% by weight, for example, ranging from 5% to 10%. The preferred composition is around the eutectoid:aluminum position of about 5% by weight. The zinc alloy coating may also have a wetting agent such as lanthanum or cerium in an amount of less than 0.1% by weight of the zinc alloy. The remainder of the coating is zinc and unavoidable impurities. Another preferred composition contains about 10% aluminium. This increased amount of aluminum provides better corrosion protection than the eutectoid composition with about 5% aluminum by weight. Other elements such as silicon and magnesium can be added to the aluminum zinc coating. More preferably, in order to optimize corrosion resistance, a good specific alloy comprises 2% to 10% aluminum and 0.2% to 3.0% magnesium, the remainder being zinc.
    [00019] Preferably, the steel wires and/or the wire rope filaments are galvanized at the end. In other words, there is no more design performed for the coated wires or wire supports. In this way, greater coating weight and better corrosion resistance are obtained together with a high production force. This is especially important for offshore mooring uses where the lifetime is around 20 years.
    [00020] As an example, the diameter of the first thread-like members is different from the second diameter of the second thread-like members. In another example, the diameter of the first wire-like members is equal to the second diameter of the second wire-like members. The diameter of wire-like members can range from 0.30 mm to 30 mm. As an example, the closed first metallic layer includes at least 20 first wire-like members and the closed second metallic layer includes more than 20 second wire-like members.
    [00021] The rotation efficiency of wire-like members is more than 90%. In a best example, the rotation efficiency is 95%, meaning loose wires only 5% resistance during wiring. Very low spin loss is achieved by combining any one or more of the characteristics as described above or later: wires are end-galvanized (crossover points are less relevant than end-drawn wires); the core and outer layers are designed with a certain stride length that increases efficiency; the cable structure has low torque; the cable can be terminated with a special fitting design.
    [00022] Preferably, the first twist direction of the first metallic layer and the second twist direction of the second metallic layer are in different lay directions. As an example, the first metallic layer is braided in the "S" direction and the second metallic layer is braided in the "Z" direction. In another example, the first metallic layer is braided in the "Z" direction and the second metallic layer is braided in the "S" direction. The torque "S" and "Z" is balanced and for this reason the hybrid cable is not rotating.
    [00023] The core element is preferably a cable made of synthetic threads. The core can have any structure known for synthetic cables. The core may have a parallel structure, a braided, a braided, an array or a braided structure or combinations of these. Preferably the core has an array or an intertwined structure, or a combination of these. In such cable structures, the cables are made of filaments. Filaments are made from strands of cables, which contain synthetic fibers. Methods of forming fiber strands, strands of yarn and strands of filaments are known in the art. The filaments themselves can also have a parallel, braided, braided, arrayed or braided structure, or a combination of these. For another description of cable structures, see, for example, "Handbook of fiber rope technology", McKenna, Hearle and O'Hear, 2004, ISBN 0-84932588-9.
    [00024] The synthetic yarns that can be employed as the core of the hybrid cable according to the invention include all the yarns, which are known for their use in fully synthetic cables. Such yarns can include yarns made from polypropylene, nylon, polyester fibers. Preferably, high modulus fiber yarns are employed, for example, liquid crystal polymer (LCP) fiber yarns, aramid, such as poly(p-phenylene terephthalamide) (known as Kevlar®), polyethylene from high molecular weight (HMwPE), ultra high molecular weight polyethylene (UHMwPE) such as Dyneema® and PBO (poly(p-phenylene-2,6-benzobisoxazole). High modulus fibers preferably have a resistance to tearing of at least 2 MPa and modulus of elasticity preferably above 90 GPa. The diameter of the core element can range from 2 mm to 300 mm.
    [00025] A plastomer, thermoplastic, braided coating and/or elastomer can also be coated or removed from the outside of the cable according to the invention. The coating has an average thickness of at least 0.1 mm, more preferably at least 0.5 mm. Said thickness is at most 50 mm, preferably at most 30 mm, more preferably at most 10 mm and most preferably at most 3 mm.
    [00026] The core element can be coated with a plastomer, thermoplastic, braided coating and/or elastomer. The plastomer may be a semi-crystalline copolymer of ethylene or propylene and one or more of C2 to C12 α-olefin comonomers and the plastomer having a density as measured according to IS01183 of between 870 and 930 kg/m3. Alternatively, the core can also be coated with a thermoplastic, preferably by means of extrusion. The thermoplastic can be high molecular weight polymers, for example, Polyethylene (PE), Polypropylene (PP), Polyurethane (PU) and Polyvinyl chloride (PVC). Employing the plastomer, thermoplastic and/or elastomer coating on the core element in the hybrid cable also ensures that the core element is protected against abrasion due to movement of the outer metal terminals when the cable is in use. Less slippage occurs between the core and the outer metallic layer.
    [00027] A preferred coating can be found in WO 2011/154415, which also provides more details on how to obtain a core element according to the present invention.
    [00028] According to a second aspect of the present invention, at this point a set of a hybrid cable and a socket is provided. The hybrid cable according to the invention is terminated at least at one of these ends by means of a socket 30. The socket has a conical-shaped space 20 as shown in Figure 2. The conical-shaped space of the socket has a conical angle of one of between 2 and 8° and a length A of between 5D and 20D when D is defined as the smallest diameter of the conical-shaped space. The steel wires have not been braided on said at least one of the ends as shown in Figure 3. The open space around the unbraided wires and the core in the hollow conical body of the socket are filled with a resin.
    [00029] The hybrid cable according to the invention fits well with the above fitting. Because of the use of the special fitting, the rope breaks at higher loads, even being better than an all-steel rope of similar diameter. Additionally, the cable is neither pulled out of the socket nor breaks at the opening of the socket, but it breaks between the sockets on the free part of the cable holder. The hybrid cable assembly with the snap works so well that we achieved rotational efficiencies of more than 95%.
    [00030] A preferred set of a hybrid cable and a snap can be found in WO 2011/083126, which also provides details on how to apply the snap.
    [00031] The cables of the invention can be used for, for example, platforms with mooring offshore or offshore installation that makes it possible to go deeper with its lighter weight compared to the cables completely in steel. The cables of the invention are lighter, stronger and thus suitable to be applied as aerial cables, for example for installations or "cable car". In contrast to conventional aerial ropes, the application of the ropes of the invention obtains a larger rope sample as well as less bending. In another example, the cable of the invention can also be applied as drag or winch cables for traction or mining winches. An existing mining winch line typically weighs around 15 kg/m. This means that the weight of the cable alone already takes up 30 tons if a 2 km long cable is in use. When a same length of cable of the invention having a weight of about 8 kg/m is employed, then the weight of the cable is only 16 tons. For that reason, the hybrid cables of the invention significantly increase the load-bearing capacity or payload and provide the possibility of deeper digging mines. Furthermore, the hybrid cables of the invention due to their light weight are also beneficial for structural constructions, for example, for bridges or stadiums, commercial fishing, cranes, elevators, installation.
    [00032] According to a third aspect of the present invention, at this point there is provided the method of producing a hybrid cable comprising a core element, a first and a second closed metallic layer, in which the cross-sectional area of the element of core is greater than the total cross-sectional area of the first and second closed metal layers. It comprises the steps of providing the core element which includes an array or composition of synthetic yarns; twisting a plurality of thread-like first members together with the core element in a first direction to form the closed first metallic layer; twisting a plurality of second wire-like members together with said core element and said closed first metallic layer in a second direction to form the closed second metallic layer. It may also comprise a step of preforming each of the yarn-like members to define a predetermined helical twist prior to the twist. It may also comprise a step of extruding the core, interlayer and cable complete with a plastomer, thermoplastic, braided cover and/or elastomer to form an outer coating of the second closed metallic layer.
    [00033] The hybrid cables of the invention are applied in particular in the case of long cables for suspended use, such as suspension or drag cables in mining, cranes and elevators, aerial cables or cables for offshore installations or use in uses in commercial and marine fishing, and offshore mooring. This is because, during such use, the weight of the rope alone already takes up a large part of its load bearing capacity and winch load capacity; the payload is correspondingly limited. For that reason, the hybrid ropes of the invention are desirable in these operations as they provide comparable performance to steel ropes and lighter weight expanding the possibilities, for example, deeper mooring in the water.

Thus, for example, the terms "comprising", "including", "containing", etc. will be read expansively and without limitation. In addition, the terms and expressions used herein have been used as terms of description and not limitation, and there is no intent to use such terms and expressions to exclude any of the equivalents of the features shown and described or portions thereof, but it is acknowledged that various modifications are possible within the scope of the claimed invention.

Accordingly, it is to be understood that while the present invention has been specifically described by preferred embodiments and optional features, modification and variation of the incorporated inventions described herein may be employed by those skilled in the art, and such modifications and variations are considered to be within the scope of this invention.

    [00046] Figure 4 is a cross-section of a hybrid cable of the invention according to the first embodiment of the invention. The invention hybrid cable 40 comprises a fiber core 42, first wire-like members 44 and second wire-like members 46. Hybrid cable 40 may have a diameter ranging from 10 mm to 400 mm. The hybrid cable 40 as illustrated in Figure 4 has a "32x7c + 26x7c + FC SsZs, SzZz or ZzSz" cable structure. The term "32x7c + 26x7c + FC SsZs" refers to a cable design with the second metallic layer (outermost layer) having 32 filaments (ie, second metallic wire-like members 46) with an "S" rotating direction. wherein each filament contains 7 filaments compacted with an "s" rotating direction, the first metallic layer having 26 filaments (i.e., first wire-like members 44) with a "Z" rotating direction, wherein each filament contains 7 compacted filaments with a rotating "s" direction and a fiber core (abbreviated as FC). The cable structure as shown in table 1 is similarly denoted. The metallic members 44.46 of the hybrid cable 40 as shown in Figure 4 have an identical size and strand filament structures. Alternatively, the metallic members can have different diameters and/or the other strand filament structures. Table 1 gives the details of some examples of hybrid cables, but does not limit the present invention.
    [00047] Core 42 is made from a plurality of high modulus polyethylene (HMPE) yarns, eg any one or more yarns of 8*1760 dTex Dyneema@ SK78 yarn, 4*1760 dTex Dyneema@ yarn or 14*1760 dTex Dyneema@ 1760 dTex SK78 yarn. Core 42 can be made from an array of interwoven filaments or continuous synthetic strands. As an example, in a first step a first part of the 12-filament braided core was produced, each filament consisting of 8*1760 dTex Dyneema@SK78 yarn. This first part of the core is super-interwoven with the 12 filaments of 4*1760 dTex Dyneema@ yarn.
    [00048] In this embodiment, the diameter of the first wire-like members 44 can be the same or different from the second wire-like members 46 (see table 1). Wire-like members 44.46 as an example illustrated in the appendix are supports having a plurality of substantially identical metal filaments. It should be understood that wire-like members may have different filament configuration. In addition, the metallic layers can include metallic thread-like members with different filament configuration. It should be understood that the metallic layers can also comprise a combination of strand filaments and single steel wires. hybrid cable 2
    [00049] Figure 5 is a cross-section of a hybrid cable of the invention according to the second embodiment of the invention. A hybrid cable of the invention 50 comprises a fiber core 52, first wire-like members 54 and second wire-like members 56. Figure 5 schematically shows, as an example, a hybrid cable having a "34 + 24" structure. + FC SZ". As a differential of the first modality, the metallic wire-like members 44.46 are each replaced by a single steel cable 54.56. The hybrid cable has a structure of "34 + 24 + FC SZ", meaning that the hybrid cable has a fiber core, the first metallic layer with an "S" rotating direction having 24 wires and the second metallic layer with a direction rotating in "Z" having 32 wires. The characteristics of some possible structures of the hydro cable are given in table 2. It should be understood that the metallic layers can also comprise a combination of strand filaments and single steel wires.



    hybrid cable 3
    [00050] Figure 6 is a cross-section of a hybrid cable of the invention according to the third embodiment of the invention. As an example, the illustrated hybrid cable has a "34 + 24 + FC SZ" structure. A hybrid cable of the invention 60 comprises a fiber core 62, a stripped thermoplastic layer 63 around the core 62, first wire-like members 64, second wire-like members 66 and a thermoplastic protective layer 68.
    [00051] As an example, a coating of an EXACT™ 0230 plastomer is stripped from the cable core employing a 45mm Collin TM single helix extruder. Polyethylene (PE) is stripped from the entire cable as a protective layer.
    [00052] It goes without saying that either only a stripped coating (and not the stripped layer on the entire rope) or only a stripped layer on the entire rope (and none of the stripped coatings) are also within the scope of the invention. Furthermore, one each additional stripping / coating can be added in the middle of the two metal layers to prevent wear in the middle of the metal layers. hybrid cable with snap
    [00053] As an example, the hybrid cable having a structure of "32 + 26 + FC SZ" is attached to a socket as shown in Figures 2 and 3. The conical shaped space of the socket has the dimensions: A = 8, 8D (D is the cable diameter) α = 2°30'.
    [00054] Also the ends of the cables are terminated with the socket. The end of the cable is placed through the small diameter opening of the fitting. And then the cable and cable strands are not braided over a distance of A + D. Consequently the cable strands and strands are dispersed in the shape of the hollow conical space of the socket. The stray, non-braided end of the cable is consequently pulled into space conically. The socket containing the stray, non-braided end of the cable is placed in a vertical position, with the general opening of the space conically shaped from the socket point upwards.
    [00055] After which an unsaturated polyester with two-component resin, eg Socket Fast Blue TM, or epoxy with two-component resin is mixed and poured into the socket, to fill the open spaces between the strands and the strands of the frayed and scattered end of the cable. The resin is allowed to cure for a period of 24 hours at room temperature (-20°C). The length of the cables is 4 m.
    [00056] The cables are tested in accordance with ISO 2307. The cables are connected through their sockets to a standard cable break tester. The rope is pretensioned 5 times to approximately 50% of the expected strength indicated by means of breaking load (BL). Consequently, the cables were tensioned to breakage. The breaking strength of the ropes is reported in table 3. Three hybrid ropes with the same configuration are individually tested and the deviation is also given in table 3. As a reference, fully enclosed steel rope/half polyester all steel rope are also listed.

    [00057] Hybrid cables tested give consistent results. The hybrid cable E-module is in the middle of the range of all steel cables and polyester cables. It should be noted that the given E-module values for the cables listed over Table 3 are typically expected values other than hybrid cable. Compared to an all steel rope having a similar diameter, the hybrid rope decreases the weight by 37 - 46% while increasing the breaking load to 4 - 17%. In contrast to the polyester rope, although the hybrid rope has 25% more linear weight, the diameter of the polyester rope is about twice that of the hybrid rope in order to obtain a similar breaking strength.
    [00058] Semi-dynamic hardening is also evaluated on 22mm hybrid cable (A) and 22mm all steel cable (filament, 35xK7) (B). The hardening values evaluated correspond to those required for the size of the mooring lines for the maintenance station, and are based on the work carried out to certify cables with synthetic fibers for these applications (Del Vecchio CJM, 1992, Light-weight materials for deep water moorings, PhD thesis University of Reading; Francois M, Davies P, 2008, Characterization of polyester mooring lines, OMAE 2008-57136). Tests to determine semi-dynamic hardening are performed as defined in both international standards (ISO 18692, 2007, Fiber ropes for offshore station keeping - Polyester) and classification society rules (Bureau Veritas, 2007, Certification of fiber ropes for deep water offshore services, NI432R01).
    [00059] The loading scheme for the semidynamic measurement is shown in Figure 7. The abscissa is the time in the unit of second (s) and the ordinate is the applied load in the unit of kN. The average load applied is 10%, 20%, 30% and 40% of the breaking load (BL) of the wire rope. The semi-dynamic hardening values of the hybrid cable (A) and the all-steel cable (B) are shown and compared in Figure 8. The semi-dynamic hardening of both cables increases significantly with increasing average load over the applied range of loads ( 10 to 40% of BL). The semi-dynamic hardening of hybrid cable (A) is 17 to 26% less than all-steel cable (B). In any case, the advantage of hybrid cable over all-steel cable appears when taking weight into account. Specific hardening is defined as the ratio of hardening to linear weight. As shown in Figure 9, the specific hardening of hybrid rope (A) is 22 to 37% higher than that of all steel rope (B) over the tested load range.
    [00060] In addition, the deformation over time at constant loads is evaluated in Figure 10. The deformation is defined as the deformation of the wire rope (elongation) under a situation of static, constant loading. A 22mm multi-strand hybrid cable (A) is compared to 13mm 8-strand all-steel cable (C) and 13mm 8-strand hybrid cable (D). The load applied on the 22mm multi-strand hybrid cable (A) is 50% BL while that on the 13mm 8-strand all-steel cable (C) and 13mm 8-strand hybrid cable (D) is 40% BL. Wire rope temperatures were maintained at about 50° for 10 days of evaluation. Deformation was measured as a change in stress (%) over time (h). As shown in Figure 10, hybrid cable (A) has a greater range than all steel cable (C) at the time of applied load which is like a core to the fiber cable. However, over time at constant load, hybrid rope (A) shows a similar load range compared to all steel rope (C). Compared to 8-strand hybrid cable (D), more load is applied on a hybrid cable of the multi-strand invention (A) (50% BL vs. 40% BL). Furthermore, the relative cross-sectional area of the core is greater in the multi-strand hybrid cable (A). Even with these factors, the strain rate of the multi-filament rope (A) is significantly low. For this reason, deformation does not become problematic over time for a hybrid cable of the invention.Reference list10 composite cable12 synthetic core14 metal sheath16 wire20 socket conical shape 30 hybrid cable terminated at its end by means of a socket40 hybrid cable 142 fiber core44 first wire-like member46 second wire-like member50 hybrid cable 252 fiber core54 first wire-like member56 second wire-like member60 hybrid cable 362 fiber core63 thermoplastic layer64 first wire-like member66 second member wire type 68 thermoplastic protection layer first wire type member second wire type member thermoplastic protection layer
