FIELD: radio engineering. ^ SUBSTANCE: in field communication cable of repeated use there are electric conductors, insulation protection cover and load-carrying element located under the above cover and made from synthetic high-strength strands. On each side of actual cable length there installed are connecting half-couplings in the housing of each of which there arranged is terminal block to which electric conductors of cable are soldered, sealing elements, as well as attachment point of load-carrying cable element. At that, in half-coupling housing there is protrusion, and attachment point of load-carrying element is ""-shaped with the middle part of cylindrical shape. Load-carrying cable element is divided into two bunches, opposite and not covering each other and wound on cylindrical part of attachment point and attached to each other after not less than one coil of winding, for example by means of the point, and edges of side parts (racks) of attachment point of load-carrying element interact with protrusion on the half-coupling housing. In order to increase the breaking strength of cable in case its structure includes four or more bunches of synthetic high-strength strands, on cylindrical part of the attachment point there are at least two connection points of bunches of strands. ^ EFFECT: increasing breaking strength of field cable with load-carrying element made from high-strength fibres. ^ 2 cl, 3 dwg |
