CW1128 External Telephone Cable

CW1128 external telephone cables are ideal for outdoor installations where an armour is not required. The cores are protected in petroleum jelly to protect against the longitudinal ingress of water whilst the PE (polyethylene) or external grade PVC sheath provide resistance against UV, sunlight, rain or snow.

CW1128 telephone cables are ideal for clipping around the outside of buildings, clipping to a catenary wire or running through ducting.

Standard conductor sizes are 0.5mm and 0.9mm, 0.6mm and 0.63mm can be manufactured to order. CW1128 is designed to be terminated in IDC connectors therefore all conductor sizes are given as the copper strand diameter.
