Product Overview
The CJPFP90/NC is a robust fire resistant marine power cable engineered for critical circuits where maximum mechanical protection must coexist with guaranteed circuit integrity during fire emergencies. It features a Mica Glass Tape + XLPE composite insulation system for fire survival, combined with a Halogen-Free (LSZH) inner sheath and collective screen. Its defining characteristic is a high-strength galvanized steel wire braid armor, providing superior resistance to crushing, impact, and tensile stress. Designed without an outer sheath, this cable delivers the ultimate defense for essential power and control systems in the most demanding and physically hazardous locations.
Key Features & Benefits
-
Certified Fire Resistance: Complies with IEC 60331, ensuring continued electrical operation of emergency circuits (e.g., pumps, alarms) for a specified period under direct flame and mechanical shock, which is crucial for life safety.
-
High-Strength Mechanical Armor: A braided armor of galvanized steel wires offers exceptional protection against crushing, pulling, and impact, ideal for exposed runs or areas with severe physical hazards.
-
Fire-Survival Core Construction: The Mica Glass Tape layer over XLPE insulation creates a heat-resistant ceramic barrier that maintains insulation integrity at extreme temperatures, preventing circuit failure during a fire.
-
Superior Fire Safety: Meets IEC 60754 (Halogen Free) and IEC 61034 (Low Smoke), drastically reducing the emission of corrosive/toxic gases and smoke opacity to facilitate safer evacuation and protect equipment.
-
EMI Protection & Durability: The collective copper screen shields against electromagnetic interference, while the single, robust LSZH inner sheath provides essential environmental and chemical resistance.
