The quality of the cable is extremely important for the efficiency of cathodic protection system, especially the anode cables. Commonly use cathodic protection cables are PVDF/HMWPE, XLPE/PVC, THHN, HMWPE etc. Cables used for cathodic protection systems must be highly corrosion resistant and capable of withstanding adverse environments to which they are exposed.

XLPE/PVC cable is the most common used cable in cathodic protection systems. It is composed of copper core covered with XLPE Insulation layer which has very good electrical, mechanical and thermal characteristics in medium voltage networks.This type of insulation has excellent chemical resistance and is also resistant to cold temperatures.The jacket layer is made of PVC material which double enhance its dielectric, water and fire proof and abrasion resistance ability.
