FIELD: electricity.
SUBSTANCE: balanced unshielded 25-paired cable of category 5e with improved characteristics includes polymer-insulated cords which are twisted in pairs, and external polymer sheath; polymer corrugated and perforated tube is arranged in the centre, and twenty five pairs are divided into five bunches, five pairs in each bunch; at that, to each bunch there introduced is five-beam polymer corrugated separating element between beams of which there arranged is one pair, and each bunch is laced into perforated band with covering of edges throughout the cable length, and all of five beams are twisted between each other around central polymer corrugated and perforated tube.
EFFECT: invention allows reducing the proximity effect of other pairs and mutual influences between pairs.
