CP Wire and Cable
Description:
CP wire and cable is mainly used in impressed current cathodic protection system. This insulated cathodic protection cable has excellent electrical properties, mechanical properties, heat aging properties, strong resistance to environmental stress and chemical corrosivity. CP wire and cable is of low water absorption and simple structure. Besides, this insulated cathodic protection cable is easy to use. There is no limit of head drop during the cable laying. The primary insulation layer is Polyvinylidenfluoride (PVDF) and the outer sleeve (the secondary insulation) layer is High Molecular Weight Polyethylene (HMWPE). PVDF or HMWPE cables are extensively used in the cathodic protection system of highly corrosive environment.
