Copper telecommunication Polyquad No. 6 CW 1280.

Telecommunication Cables / Telecommunication Copper Cables / UK Telecom Cables

Tratos is a long-established manufacturer of Telecommunication Cables, a family of cables used for the transmission of Data, Information, Voice and Images. Production at Tratos covers almost all the installation needs of Telecommunication Cabling.

These cables are cellular-polyethylene insulated jelly filled colour coded star quad No.6 cables with copper conductors stranded into a compact and circular assembly as detailed in BT Specification CW 1280. The assembly of quads are covered with a polyester wrapping tape two rip cords are inserted under the sheath to aid stripping and termination of the cable. The robust polyethylene sheath used by Tratos ensures outstanding pliability and protection.

Tratos has developed this cable to have the optimum balance of properties, toughness to withstand pulling into ducts combined with a smooth, low coefficient of friction, surface, to ease installation and prevent jamming.

Conductor sizes available are 0.63 mm and 0.9 mm. The standard number of quads available is from 7 to 520 (0.63 mm) and 7 to 272 (0.9 mm) but other numbers of quads are available on request. Tratos also manufacture similar cables in traditional paired construction.

When specially ordered, cables can be supplied with an aluminium foil moisture barrier in combination with the polyethylene sheath.

The cable meets or exceeds the requirements of CW 1280.
