Cathodic Protection Cable is a single conductor cable that is intended to carry a DC current to anodes and cathodes in a cathodic protection system. This specification describes a stranded copper conductor with dual insulation.
The primary layer of insulation is composed of HALAR (also known as ECTFE) a fluoropolymer material that has exceptional chemical resistance in the presence of chlorine, sulfuric acid, and hydrochloric acid.
The outer insulation layer is a low-density high molecular weight polyethylene (HMWPE), which exhibits superior dielectric and tensile strength, provides mechanical protection to the primary layer, and withstands considerable abuse during installation.
Construction
Conductor: Stranded bare or tinned copper conductor conforms to ASTM Spec B-3 and B-8
Primary Insulation: A natural ECTFE fluoropolymer (HALAR) shall be extruded around the conductor
Jacketing Insulation: High molecular weight polyethylene (HMWPE) shall be extruded over the HALAR primary insulation, conforms to ASTM D-1248
Applications
Our Cathodic Protection Cable (CPC) is suitable for direct burial for cathodic protection systems for pipelines, storage tanks, pilings, well casings, cables, marine crafts, and other buried or water submerged metallic structures.
Features
CPC provides superior resistance to:
- Abrasions
- Crushing
- Chemicals
- Oils
- Sun Damage
- Moisture
Temperature
Operating temperature is 70 degrees Celsius
Rating
Voltage is 600 volts
Packaging
1000 ft, 2500 ft, 3500 ft standard reel lengths; custom lengths are available upon request. Identified by surface printing indicating manufacturer, conductor size, and insulation type; custom print legends are available upon request.
HALAR cathodic protection cable from Performance Wire and Cable is made of a fluoropolymer insulation that exhibits superior chemical resistance. Made with dual insulation, HALAR wire can be used in any situation where chlorine and hydrogen gases are present.
Our HALAR cable is made with a primary layer, which is most resistant to chlorine, sulfuric acid and hydrochloric acid – ensuring great protection and resistance. Following the primary layer is a high molecular weight polyethylene (HMWPE) insulation, which provides pliable strength and allows considerable abuse during installation. The HMWPE jacketing provides mechanical protection as well. HALAR cathodic protection cable is available in sizes 8 AWG through 1/0 AWG.
Additional HALAR Applications and Specifications:
- HALAR / HMWPE cables are used as deep anode lead wires where chlorine and hydrogen gases are generated.
- The cable can be directly installed in fresh, brackish, or salt waters.
- Primary installation is a homogeneous 20 mil wall of natural ECTFE fluoropolymer (HALAR) shall be extruded around the conductor.
- Jacket is a 65 mil wall of high molecular weight polyethylene (HMWPE) shall be extruded around the primary insulation.
- For identification purposes, the cable shall be surface printed with: “Manufacturer name Conductor size AWG, HALAR / HMWPE CATHODIC PROTECTION CABLE.”
