HMWPE Cathodic Protection Cable Application HMWPE insulated cable is composed of copper wire, which is covered by High Molecular Weight Polyethylene (HMWPE) high thickness insulation. The copper wire is stranded and annealed to permit extra flexibility. The polyethylene on the cable is approximately twice as thick as on conventional HMWPE wire; it serving as both electrical insulator and mechanical cover for the conductor. This provides cable with outstanding dielectric strength and moisture resistance. During installation, the cable can withstand considerable mechanical abuse without risk of damage to the copper electrical conductor. The polyethylene cover is also chemically resistant and protects against most organic and inorganic substances. Availability HMWPE cable is offered in a variety of sizes. It can be used as a header cable on cathodic protection systems or to make anode-lead or negative-return connections. The thick polyethylene cover permits direct burial of the cable in native soils or submersion in freshwater. The cable exhibits superior flexibility and can be bent without risk of notch propagation. It is not recommended for use in environments containing chlorine, hydrochloric acid, or petroleum hydrocarbons.

HMWPE Cathodic Protection Cable
Application
HMWPE insulated cable is composed of copper wire, which is covered by High Molecular Weight Polyethylene (HMWPE) high thickness insulation. The copper wire is stranded and annealed to permit extra flexibility. The polyethylene on the cable is approximately twice as thick as on conventional HMWPE wire; it serving as both electrical insulator and mechanical cover for the conductor. This provides cable with outstanding dielectric strength and moisture resistance. During installation, the cable can withstand considerable mechanical abuse without risk of damage to the copper electrical conductor.
The polyethylene cover is also chemically resistant and protects against most organic and inorganic substances.
Availability
HMWPE cable is offered in a variety of sizes. It can be used as a header cable on cathodic protection systems or to make anode-lead or negative-return connections. The thick polyethylene cover permits direct burial of the cable in native soils or submersion in freshwater. The cable exhibits superior flexibility and can be bent without risk of notch propagation. It is not recommended for use in environments containing chlorine, hydrochloric acid, or petroleum hydrocarbons.
