CW1128 External Telephone Cable

CW1128 external telephone cables are suitable for installation outdoors where an armoured cable is not necessary. They offer a lightweight, compact, tough solution for cables that will have to endure a variety of weather conditions, from rain and snow to bright sunlight.

CW1128 telephone cables are ideal for clipping around the outside of buildings or running through ducting.

The duct grade outer sheath is made from tough, durable polyethylene which is also UV and sunlight resistant. The pairs are bedded in petroleum jelly to protect against the ingress of moisture.

Available in 2, 3, 5, 10, 20, 30, 50 or 100 pair versions in either 0.5mm or 0.9mm conductor sizes.
