Cathodic Protection Cable (CPC) is used in Cathodic protection systems designed to protect steel, water or fuel pipelines and storage tanks, steel pier piles, ships, offshore platforms and onshore well casings from corrosion. CPC helps make sure your metal lasts as long as possible when exposed to the earth’s electrical charge.
CPC typically consists of a stranded copper conductor insulated from the surrounding soil by one of the following:
- A single layer of High Molecular Weight Polyethylene (HMWPE) insulation which in most applications is 0.110″ thick (110 mils).
- A fluoropolymer insulation, usually 0.020″ (20 mils) of Halar (ECTFE) protected by a 0.065″ (65 mils) Polyethylene (HMWPE) jacket is typically used where halogen gases such as fluorine, chlorine, bromine etc. are present and concentrated around the anode and the cable. These types of cables are commonly called “Halar” or “Kynar” Cathodic Protection Cables.
