    The invention relates to the production technology of cable products H can be used in the manufacture of electrical cables with hm-neutral insulation in a metal sheath.
    The purpose of the invention is to increase the radiation resistance of the cable.
    The proposed method consists in pre-fabricating a billet with a diameter much larger than the diameter of the finished cable, a billet-bluing of the billet by operations, starting at least from the second, forging under a hammer and / or rolling, Lazy annealing, and in quality. Conductor and shell materials use titanium, containing not more than 0.03% nitrogen, 0.25% oxygen, 0.015% Hydrogen, 0.10% carbon and 0.30% iron, with tensile strength not exceeding 540 N / mm and elongation at break of at least 22%, and each annealing is carried out in an atmosphere of inert gas at 600-640 ° C for at least 15 minutes, followed by slow cooling at ambient temperature also for at least 15 minutes.
    In addition, as the material of the conductors and the shell can be. titanium was used with a smaller amount of impurities (no more than 0.03% nitrogen, Oj, 18% oxygen, 0.015% hydrogen,
    0.10% of carbon and 0.20% of iron), the tensile strength of which when stretched is no more than 410 N / mm and elongation at a discharge of not less than 30%.
    PRI me R. A preformed billet with a diameter of 13.75 mm with an inner conductor and a titanium shell Grad 2 with a high content of impurities is subjected to elongation to a diameter of 12.52 mm (an elongation of 20%). The extruded billet is annealed in argon for 15 minutes at ambient temperature.
    After annealing, the workpiece is subjected to elongation by forging under a hammer to a diameter of 10.8 mm (elongation of about 35%) and is again annealed for 15 minutes at, and then cooled for 15 minutes at that temperature of the surrounding medium.
    Then, successive lengthening operations up to diamegres 9.3-, 8i 6.90-, 5.95; 5.15; 4.40 3.80 and 3.20 mm divided by each other
    the same annealing. Get a cable with a sheath having an excellent surface without a trench.
    If titanium is placed with a smaller number of impurities (Trad-1), it is possible to slightly increase the degree of elongation for each lengthening operation and, consequently, reduce the number of these operations.
    With the same preformed workpiece, it is also possible to carry out lengthening operations using the rolling method. In this case, it is possible to obtain more significant individual extensions and, consequently, to obtain a cable with a smaller number of operations, however, for this, rolls with grooves specially adapted for cables with sheath and with a conductor made of titanium should be arranged.
    If necessary, you can use other insulating materials instead of magnetism, such as alumina.
    The invention is applied, in particular, in the manufacture of cables for measuring neutron fluxes during radiation, since the emitted titanium is deactivated twice as fast as the previously used metals.
