Cathodic Protection Cable

---

The quality of the cable is extremely important for the efficiency of cathodic protection system, specially the anode cables. Commonly use cathodic protection cables are PVC/PVC, PE/PVC, EPR/CSP, XLPE/PVC, XLPE/PVC/SWA/PVC, PVDF/HMWPE/ PVC/ Nylon/ PVC. PE/ Nylon/ PE. Cables used for cathodic protection systems must be highly corrosion resistant and capable of withstanding adverse environments to which they are exposed to on a consistent basis. High Molecular Weight Polyethylene (HMWPE) is suitable for most environments. In saline environment, we recommend KYNAR/HMWPE or HALAR/HMWPE cables, which are dual extruded highly chlorine resistant power cables. CCP supplies all types of cables used in cathodic protection system. 

HMWPE Cable for Cathodic Protection: High Molecular Weight Polyethylene (HMW-PE) Cathodic Protection Cables: 600 Volts, Single Conductor, Stranded Copper. Stranded copper conductor conforms to ASTM Specification B-8. Insulation is high molecular weight polyethylene conforming to ASTM D-1248, Type 1, Class A, Category 5, Grades E4 & E5. Tensile Strengths Jl, J3. Available with high density polyethylene (Types II, III, IV) Class B & C (all colors).

Application : A direct burial DC cable for use in cathodic protection applications such as anode lead wires, header cables, structure connections, test leads and more. The product can also be used for submerged installations in water tanks, offshore structures and other similar applications. The polyethylene insulation is durable, abrasion resistant and flexible but has temperature and chemical limitations.

Halar/HMWPE Cable: Cathodic Protection Cables, Primary Halar Insulation, HMW (High Molecular Weight) Polyethylene Jacket.

Stranded bare copper conductor conforms to ASTM Specification B-8. An insulation of homogeneous wall of natural ECTFE fluoropolymer (Halar) shall be extruded over the conductor, jacket insulation is high molecular weight polyethylene conforming to ASTM-D-1248, Type 1, Class A, Category 5, Grades E4 and E5. Tensile Strengths Jl, J3. Available with high density polyethylene (Types II, III, IV) Class B and C (all colors). Surface printed. Custom printing available.

Kynar/HMWPE: Cathodic Protection Cables, Primary Kynar Insulation, HMW (High Molecular Weight) Polyethylene Jacket. Stranded bare copper conductor conforms to ASTM Specification B-8. A homogeneous wall of natural PVDF fluoropolymer (Kynar) shall be extruded over the conductor.

An Insulation of high molecular weight polyethylene conforming to ASTM-D-1248, Type 1, Class A, Category 5, Grades E4 and E5. Tensile Strengths Jl, J3. Available with high density polyethylene (Types II, III, IV) Class B and C (all colors). Surface printed. Custom printing available.

Application: A direct earth burial, DC lead, cathodic protection cable for use in deep anode groundbed installations, designed to withstand corrosive gases.

CP Cables can have several layers of coating on them. In addition to the HMWPE layer (which can be used alone for CPC), one of the most crucial layers is fluoropolymer insulation, which is often then covered with an HMWPE jacket. More often then not CP cables have two different types of fluoropolymers: ECTFE (Halar) and PVDF(Kynar) respectively
