FIELD: electricity.
SUBSTANCE: in symmetrical four-pair cable containing conductors in polymer insulation, shielded pairs, a drain conductor, a common sheath from foil and braiding and an external polymer cover, one of the pairs is chosen as a central one and is put into a metal polymer sheath with metal to the outer side with longitudinal overlapping of edges throughout the cable length and a metal band with overlapping of edges throughout the cable length, and around this sheath there placed are the rest three pairs of the same diameter, each of which is placed in the metal polymer sheath with metal to the outer side with overlapping of edges throughout the cable length and separated from each other with metal polymer tubular elements with metal to the outer side, which do not exceed as to the size of diameter of each pair; the drain conductor is located at one of the metal polymer tubular elements.
EFFECT: invention allows reducing mutual influences between pairs and simplifying access to each conductor.
