Product Specification

CW1128 jelly filled telephone cable is used to interconnect equipment in fixed installations. The petroleum jelly filling (PJF) acts as a water barrier so that the cable can be used in wet areas. The duct grade outer sheath is made from tough, durable polyethylene which is also UV and sunlight resistant. 

These CW1128 cables are suitable for use in ducts or outdoors where an armoured cable is not required. Ideal for clipping around the outside of buildings or running through ducting. Not recommended for direct burial applications. They offer a lightweight, compact and tough solution where cables are needed that will have to endure a variety of weather conditions.
