FIELD: radio engineering, communication.SUBSTANCE: communication cable has at least one pair of conductors configured to transmit a signal, insulated from each other by inner insulation and twisted into a spiral which is coated by outer insulation such that it fills all the empty space between the insulated conductors, wherein the conductors are twisted into a spiral with pitch distance of 10-80 mm, and the inner and outer insulation is in form of high-frequency polymeric dielectric materials selected from polyolefins, which are similar to each other, with addition of a heat stabiliser - 0.05-0.2% diaphene NN and a light stabiliser - 1-3% technical carbon to the outer insulation.EFFECT: longer service life of the cable, high reliability of the cable by endowing it with high resistance to cross talk, high versatility of the cable owing to high breaking resistance, resistance to unfavourable external factors, design of a structure which makes cabling easy at any suitable surface and structures.9 cl, 4 dwg |
