1. Product Overview
This is a high-performance HMWPE (High Molecular Weight Polyethylene) insulated copper cable, specially designed for impressed current cathodic protection (ICCP) systems. It provides reliable dielectric protection for copper conductors, ensuring stable electrical connection between cathodes (protected structures) and anodes (sacrificial components) in long-term underground, marine and industrial environments.
