20 PAIR TELEPHONE CABLE SPECIFICATIONS AND DETAILS

Overview 

The armoured telephone cables are used for external connection of telephone systems and other communications equipment where the added protection of steel wire armouring is needed. This cable is ideally suited for direct burial.

Their outer sheath is made from tough, durable polyethylene or external grade PVC which is UV and sunlight resistant. The cores are bedded in petroleum jelly to protect against the ingress of moisture.

This external grade armoured telephone cable is available in 5, 10, 20, 50 or 100 pair versions, in either 0.5mm or 0.9mm conductor sizes.

External armoured cable primarily designed for the interconnection of telephone equipment. Suitable for direct burial. UV and moisture resistant. In addition, you can use these cables to interconnect other communication and control equipment or for low-level signalling applications.
