CHEPJ/NC Fire Resistant Marine Communication Cable
Product Overview
The CHEPJ/NC is a premium Fire Resistant and Low Smoke Halogen Free (LSHF) marine communication cable designed for the most critical safety circuits. It utilizes a robust Mica Glass Tape and EPR (Ethylene Propylene Rubber) dual-layer insulation system to ensure circuit integrity during fire, meeting the stringent IEC 60331 standard. Combined with a Cross-linked Polyolefin (SHF2) sheath, it offers superior fire safety, environmental resistance, and long-term reliability for essential systems on ships, offshore platforms, and in hazardous industrial plants.
