PeT Solid Local Network Cable PACW/solid polyethylene insulation/PJ filled/polyethylene sheath External Telephone Cable (Complies with BT Specification CW1326)
Application The cable is designed primarily for installing in ducts in the ‘D’ or Secondary side of local telecommunications networks. If required by the customer, the cable can be supplied with an aluminium/polymer-coated tape applied longitudinally over the paper core wrap acting as a moisture barrier. There are various other options available including a figure of eight type sheathed cable incorporating a steel support strand for use in aerial applications, and a galvanised steel wire armoured version suitable for direct burial.

Note 1: For screened cables of 20 pairs or less the maximum average mutual capacitance shall not apply and the maximum for 99% of cases shall be increased by 3nF. Note 2: For screened cables the maximum overall diameter may be increased by 1.5mm.
Insulation Resistance Insulation resistance measurements shall be made with not less than 500 volts D.C. After steady electrification for one minute the insulation resistance measured between each conductor and the remaining conductors connected together shall be not less than 1500 megohms per 1000 metres at 20°C.
Capacitance Unbalance
Not more than 1% of the corrected capacitance unbalance measurements between adjacent pairs shall exceed the following values: Two-Pair (Quad) Cable 800pF. All other sizes 275pF. Pair Colour Scheme, Unit Binder Colours and Cable Make-up Cabling Element No.
