BLENDED DESIGN OF SHIELDED SYMMETRICAL FOUR-PAIR CABLE WITH B-SHAPED MODULES AND REINFORCED OPTICAL CABLES Russian patent published in 2014 - IPC H01B11/00 

Abstract RU 2534044 C1

FIELD: electricity.

SUBSTANCE: symmetrical four-pair cable comprises polymer-insulated strands twisted into pairs with outer polymer coating, each two pairs are placed into B-shaped modules, besides, in each window of a B-shaped module there is one pair, windows of each B-shaped module are directed into opposite directions, and each B-shaped module is made of a perforated polymer tape, ends of which are closed in the middle of the tape. Polymer tape is made as a metallopolymeric tape with metal coating outside, B-shaped modules are twisted around the drain conductor, ends of B-form of each module are covered by reinforced modules with optical fibre, at the boundary between B-shaped modules at each side there are reinforced modules with optical fibre, on top of the B-shaped modules and reinforced modules with optical fibre there is a bimetal tape, a sheath and polymer coating along the whole length of the cable.

EFFECT: reducing mutual influence between pairs.
