UNSHIELDED SYMMETRICAL FOUR-PAIR CABLE OF CATEGORY 6 Russian patent published in 2016 - IPC H01B11/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in makeups of symmetric communication cables within a shared network or structured cable systems. Unshielded symmetrical four-pair cable of 6 category comprises strands in polymer insulation, packed in pairs with strand pitches, with external polymer shell, one of the pairs is central in polymer dividing band, three other pairs are twisted around it, each of which is divided by polymer element whose dimensions are limited by pair diameter, and separating polymer band is applied on central pair with overlapping edges along the entire length, each of four pairs is placed in polymer perforated tape with overlapping edges along the entire cable length, and central pair is additionally placed into the second polymer perforated tape with overlapping edges along the entire cable length, and separating elements also have perforated shell.

EFFECT: invention ensures reduction of influence between pairs due to mutual arrangement thereof.
