    Telephone Cables to CW1128 Specification

    Product Code: CW1128 TELEPHONE

    Product Description

    Manufactured to BT (British Telecom) Standard CW1128.

    Solid Copper Conductor / Cellular Polyethylene Insulated / Petroleum Jelly Filled / Paper Taped / Polyethylene Sheathed.

    These cables are designed and most commonly used for the interconnection of telecommunication equipment. However, electricians have also found that these cables are useful in other applications such as low level signalling and where the interconnection of control and communication equipment is required.

    These cables are suitable for installation in outdoor conditions where the mechanical protection of an armoured cable is not required. They are particularly well suited for being clipped around buildings as the PE sheath is tough, durable and UV resistant.
