CKJP95/NC XLPE Insulation Low Smoke Halogen Free Fire Resistant Screened Marine Control Cable
Product Overview
The CKJP95/NC is an armored, fire-performance marine control cable designed for critical circuits in hazardous environments. Featuring XLPE insulation with mica glass tape, copper screening, and galvanized steel wire armor, it delivers exceptional fire resistance (IEC 60331), low smoke toxicity (IEC 61034/IEC 60754), and EMI protection. The halogen-free thermoset outer sheath (SHF2) ensures superior durability in extreme conditions.
