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.

Armoured cable typically refers to a special type of cable that’s also known as SWA cable or steel wire armoured (SWA) cable. YUXI typical armoured cable is XLPE/PVC/SWA/PVC which is composed of copper wire covered by cross linked polyethylene (XLPE), PVC bedding, galvanised steel wire armouring and PVC jacket. 

These are specially-built, hardy power cables protective layer can be added to any structure of the cable to increase the mechanical strength of the cable and improve the erosion resistance. In addition, the purpose of adding armour layer to the cable is to enhance the tensile strength, compressive strength, etc., which can protect the cable and prolong its service life.
