Product Overview
The CJPJP85/NC is a premium-grade, double-sheathed fire resistant cable engineered for the most critical and demanding safety circuits where circuit integrity during fire must be coupled with exceptional long-term sheath durability. It features the essential Mica Glass Tape + XLPE fire-survival insulation, but distinguishes itself with a complete sheathing system of Cross-linked Polyolefin (SHF2) for both inner and outer layers. This, combined with flexible tinned copper braid armor and a collective screen, provides an unparalleled solution that ensures continuous operation in a fire (IEC 60331) while offering maximum resistance to heat deformation, mechanical stress, and harsh environmental conditions.
Key Features & Benefits
-
Certified Fire Resistance (IEC 60331): Guarantees that essential circuits (emergency lighting, fire alarms, shutdown systems) remain operational for a specified period under direct flame and impact, which is vital for life safety and asset protection.
-
Ultimate Sheath Durability with Full SHF2: Utilizes Cross-linked Polyolefin (SHF2) for both inner and outer sheaths, providing superior, long-term resistance to high temperatures, cracking, deformation, and chemical exposure compared to standard thermoplastic materials.
-
Fire-Survival Core Technology: The Mica Glass Tape layer over XLPE insulation forms a robust, heat-resistant ceramic barrier that maintains electrical insulation at extreme temperatures, preventing circuit failure during a fire event.
-
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 and minimize secondary damage.
-
Flexible & Corrosion-Resistant Armor: A braid of tinned copper wires offers excellent flexibility for installation, ease of termination, and reliable corrosion resistance in humid and saline marine atmospheres.
