Cathodic Protection Cables

Cathodic protection (CP) is a method of corrosion control that can be applied to buried and submerged metallic structures. It is normally used in conjunction with coatings and can be considered as a secondary corrosion control technique.

The primary corrosion control method on any given structure is normally a coating system which can be between 50 and 99 % efficient depending upon age, type, method of installation, etc. A properly designed and maintained cathodic protection system will take up the remainder resulting in a 100 % efficient corrosion protection system.

CP Cable is used as direct earth burial DC feeder cable in cathodic protection systems to protect against galvanic and electrolytic corrosion of metallic objects - such as storage tanks, pipelines, wells and ocean vessels - that are buried or submerged in water.

It has excellent abrasion, crush, chemical, oil, sunlight and moisture resistance. PVDF insulation offers additional resistance to corrosive gases and brackish water, and can be used for deep anode ground-bed installations. Cathodic protection can protect all types of buried and submerged metallic structures.
