FIELD: electricity.
SUBSTANCE: symmetric four-pair cable includes cords in polymer insulation, which are twisted in pairs with various pitches, with outer polymer sheath; one of the pairs is central in polymer dividing band; three other pairs are twisted around it, each of which is separated with polymer element the dimensions of which are restricted with diameter of the pair, and separating polymer band is put on central pair so that edges are overlapped throughout the length.
EFFECT: reducing mutual influence between pairs.
