Copper telecommunication CW1280/CW1252 Aerial PET-PEQ

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.

Mechanically these cables contain integral cable suspension and special sheaths as demanded by the application of combined self supporting (Figure of eight cross-section) aerial cables as detailed in BT Specification CW 1252.  Tratos can advise on the selection of the correct strength member to support the weight of the cable for the prescribed span and to withstand any addition loading caused by wind, ice and perching birds.

Electrically these cables are cellular-polyethylene insulated jelly filled colour coded quad cables with copper conductors stranded into a compact and circular assembly as detailed in BT Specification CW 1280.

Conductor sizes available are 0.63 mm and 0.9 mm. The standard number of quads available is from 7 to 520 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.

A shotgun-protected cable containing a corrugated steel tape can also be provided if specially ordered.

The cable meets or exceeds the requirements of CW 1252 and CW 1280.
