Product Overview
The CJVP80/NA is a Fire Resistant (FR) marine power cable designed to ensure circuit integrity for critical safety systems during a fire emergency. It combines a Mica Glass Tape + XLPE composite insulation system, certified to IEC 60331, with a standard PVC inner sheath and a flexible, corrosion-resistant tinned copper wire braid armor. This cost-effective shielded solution provides reliable, continuous power to essential circuits under fire conditions, making it suitable for a wide range of marine and industrial applications where standard sheath materials are acceptable.
Key Features & Benefits
-
Certified Fire Resistance (IEC 60331): Ensures vital emergency circuits (e.g., emergency lighting, fire alarms, pump systems) remain operational for a specified duration under direct flame and mechanical shock, which is critical for life safety.
-
Flexible & Corrosion-Resistant Armor: The braided armor of tinned copper wires offers excellent flexibility for easier installation and routing, along with inherent corrosion resistance suitable for marine and humid environments.
-
Fire-Survival Core Technology: 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 Construction: Utilizes a proven PVC inner sheath, offering good mechanical protection and environmental resistance at a competitive price point for applications not requiring halogen-free materials.
-
Effective EMI Shielding: The integrated collective copper screen protects against electromagnetic interference, ensuring signal integrity for power and control systems.
