HMWPE insulated cable is composed of copperwire, which is covered by High Molecular WeightPolyethylene (HMWPE) high thickness insulation.The copper wire is stranded and annealed to permitextra flexibility. The polyethylene on the cable isapproximately twice as thick as on conventionalHMWPE wire; it serving as both electrical insulatorand mechanical cover for the conductor. Thisprovides cable with outstanding dielectric strengthand moisture resistance. During installation, thecable can withstand considerable mechanical abuse without risk of damage to the copperelectrical conductor.The polyethylene cover is also chemically resistant and protects against most organic andinorganic substances.AvailabilityHMWPE cable is offered in a variety of sizes. It can be used as a header cable on cathodicprotection systems or to make anode-lead or negative-return connections. The thick polyethylenecover permits direct burial of the cable in native soils or submersion in freshwater. The cableexhibits superior flexibility and can be bent without risk of notch propagation. It is notrecommended for use in environments containing chlorine, hydrochloric acid, or petroleumhydrocarbons.
