摘要

The claimed technical solution relates to the cable industry, namely to a multi-pair electrical cable connection and can be used in the construction of telecommunication cables, namely a cable designs local communication frequency (digital) intended to operate on networks of subscriber access equipped digital subscriber sealing systems. xDSL (including ADSL, ADSL2 +, VDSL), cable systems structured in the frequency range up to 100 MHz at a transmission speed of 100 Mbit / s. local communication cable high frequency digital transmission systems for broadband networks in the frequency range up to 100 MHz with copper conductive strands twisted into pairs of unidirectional twist, with a solid plastic or solid insulation polymer compositions not containing halogen, or a three-layer film-porous-film polyethylene insulated, shielded, with water blocking elements or without them, polyethylene or polyvinyl chloride plastic shell (including low flammability and izhennoy fire) or sheathed polymeric compositions not containing halogen, with a protective coating or without, the isolated conductive strands twisted in pairs with a unidirectional twist coordinated steps between 10-30 mm, each pair within the three (four, five) beam pair is made with its pitch of: the first - 12 ± 0,05 mm, a second pair of -15 ± 0,05 mm, the third pair - 17 ± 0,05 mm, a fourth pair - 21 ± 0,05 mm, a fifth pair - 29 ± 0,05 mm. The claimed technical solution extends the scope of the cables due to changes stranding system (administration of three or four pairs of elementary beams), 25 and 75-pair cable cores and to reduce the magnitude of isolated steps in the range of twist pair lived within 10-30 mm; increases fire safety cable through the use of polymeric materials in cables not containing halogens, as well as enhancing the thermal barrier glass tape, a mica tape.
