Product Overview
The CJVP82/NA is a robust, double-sheathed fire resistant marine cable designed to provide enhanced mechanical protection and environmental sealing for critical circuits that must maintain operation during a fire. It integrates a Mica Glass Tape + XLPE composite insulation system (IEC 60331) with a dual-layer PVC sheath and a flexible tinned copper wire braid armor. This construction offers a cost-effective and durable solution, ensuring circuit integrity for emergency systems while providing superior resistance to abrasion, impact, and moisture in demanding marine and industrial environments where standard sheath materials are suitable.
Key Features & Benefits
-
Certified Fire Resistance (IEC 60331): Guarantees that essential safety circuits (e.g., emergency lighting, fire alarms, pump controls) remain functional for a specified period under direct flame exposure, which is crucial for life safety and emergency response.
-
Enhanced Mechanical Protection: Features both an inner and outer sheath made of Polyvinyl Chloride (PVC), offering superior resistance to abrasion, crushing, oils, and harsh environmental conditions compared to single-sheathed designs.
-
Flexible & Corrosion-Resistant Armor: The braided armor of tinned copper wires provides excellent flexibility for easier installation and routing, along with reliable corrosion resistance in humid and saline atmospheres.
-
Fire-Survival Core Construction: The Mica Glass Tape layer over XLPE insulation forms a robust, heat-resistant barrier that maintains electrical insulation integrity at extreme temperatures, preventing circuit failure during a fire.
-
Cost-Effective Reliability: Utilizes proven PVC sheathing materials, delivering durable protection and fire-resistant performance at a competitive price point for applications not requiring halogen-free specifications.
