Product Overview
The CJVP90/NA is a heavy-duty fire resistant marine power cable engineered to ensure circuit integrity for the most critical safety systems under severe mechanical stress and fire conditions. It features the essential Mica Glass Tape + XLPE composite insulation, certified to maintain operation during a fire (IEC 60331). Its core is protected by a standard PVC inner sheath and, most notably, a high-strength galvanized steel wire braid armor for maximum crush and impact resistance. This cost-effective shielded cable is designed to provide reliable power to emergency circuits in exposed, high-risk marine and industrial locations where extreme durability and fire survival are paramount.
Key Features & Benefits
-
Certified Fire Resistance (IEC 60331): Guarantees that vital emergency circuits (e.g., emergency generator feeds, fire pump power, alarm systems) remain operational for a specified duration under direct flame and mechanical shock, critical for life safety.
-
Maximum Mechanical Protection: A braided armor of galvanized steel wires provides supreme protection against crushing, impact, and pulling forces, making it ideal for exposed cable runs or areas with severe physical hazards.
-
Fire-Survival Core Construction: The Mica Glass Tape layer over XLPE insulation forms a robust, heat-resistant ceramic barrier that maintains electrical insulation integrity at extreme temperatures, preventing circuit failure during a fire.
-
Cost-Effective & Durable Sheathing: Utilizes a proven PVC inner sheath, offering good resistance to abrasion, moisture, and oils at a competitive price point for applications where halogen-free materials are not mandated.
-
Effective EMI Shielding: The integrated collective copper screen protects against electromagnetic interference, ensuring signal integrity for power and control circuits.
