Product Overview
The CJPJP90/NC is a heavy-duty fire resistant marine cable engineered for the most demanding safety-critical installations where guaranteed circuit integrity under fire must be combined with extreme mechanical protection. It features a fire-survival core of Mica Glass Tape + XLPE insulation, an enhanced Cross-linked Polyolefin (SHF2) inner sheath for superior thermal and mechanical resistance, and a robust galvanized steel wire braid armor. This cable ensures vital emergency systems remain operational during a fire (IEC 60331) while providing unmatched defense against crushing, impact, and harsh environmental conditions in exposed or high-risk locations.
Key Features & Benefits
-
Certified Fire Resistance (IEC 60331): Ensures continuous operation of essential circuits (emergency lighting, fire pumps, alarms) under direct flame and mechanical shock, a critical requirement for life safety and asset protection.
-
High-Strength Steel Armor: A braided armor of galvanized steel wires provides maximum resistance to crushing, impact, and tensile stress, ideal for exposed cable runs or areas with severe physical hazards.
-
Enhanced Sheath Performance: The Cross-linked Polyolefin (SHF2) inner sheath offers outstanding resistance to high temperatures, deformation, and cracking, ensuring long-term sheath integrity in demanding environments.
-
Fire-Survival Core Construction: The Mica Glass Tape layer over XLPE insulation forms a robust, heat-resistant ceramic barrier, maintaining electrical insulation and preventing circuit failure during a fire.
-
Superior Fire Safety (LSZH): Complies with IEC 60754 (Halogen Free) and IEC 61034 (Low Smoke), drastically reducing the emission of corrosive/toxic gases and smoke density to facilitate safer evacuation.
