FIELD: electricity.
SUBSTANCE: symmetric four-pair cable includes cords in polymer insulation which are twisted in pairs with various pitches and having an outer polymer sheath; one of the pairs is the central and is located inside a three-ray dielectric element between the rays whereof the other three pairs are located; the ray size is not in excess of the pair diameter, the three-ray dielectric element edges joining performed along the whole length with edge overlapping.
EFFECT: invention allows to reduce mutual influence between the pairs.
