Product Overview
The CJVP92/NA is a heavy-duty, double-protected fire resistant marine cable engineered for the most demanding applications where circuit integrity during a fire must be guaranteed alongside maximum mechanical and environmental defense. It combines the fire-survival Mica/XLPE insulated core (IEC 60331) with the robust protection of a dual-layer PVC sheath and a high-strength galvanized steel wire braid armor. This construction provides an exceptionally durable and cost-effective solution for ensuring continuous power to critical safety systems in the harshest marine and industrial environments where extreme physical protection is required.
Key Features & Benefits
-
Certified Fire Resistance (IEC 60331): Guarantees that essential emergency circuits (e.g., fire pumps, emergency lighting, alarm systems) remain operational for a specified duration under direct flame and impact, which is critical for life safety and emergency response.
-
Maximum Mechanical & Environmental Protection: A high-strength galvanized steel wire braid armor provides ultimate resistance to crushing and impact, while the dual-layer PVC sheath offers superior resistance to abrasion, moisture, oils, and chemicals for long-term durability.
-
Fire-Survival Core Technology: 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.
-
Proven & Cost-Effective Sheathing: Utilizes durable Polyvinyl Chloride (PVC) for both inner and outer sheaths, delivering excellent protective performance and value for applications where halogen-free materials are not specifically required.
-
Effective EMI Shielding: The integrated collective copper screen protects against electromagnetic interference, ensuring signal integrity for power and control systems.
