Product Overview
The CJ82/NA is a robust, fire resistant marine power cable featuring a simplified and compact construction without a separate inner sheath. It is built around a core of Mica Glass Tape + XLPE composite insulation to ensure circuit integrity during fire (IEC 60331). The insulated cores are directly protected by a flexible tinned copper wire braid armor, which is then over-sheathed with PVC. This streamlined design offers a cost-effective and durable solution for essential power circuits, providing certified fire resistance, EMI protection, and mechanical strength in a single, efficient package for demanding marine and industrial environments.
Key Features & Benefits
-
Certified Fire Resistance (IEC 60331): Guarantees that critical emergency circuits remain operational for a specified period under fire conditions, which is essential for life safety systems such as emergency lighting and fire alarms.
-
Compact & Efficient Design: The construction omits a separate inner sheath, resulting in a more compact cable that is potentially lighter and more cost-effective while maintaining core protection through the armor and outer sheath.
-
Flexible & Corrosion-Resistant Armor: The braided armor of tinned copper wires provides excellent flexibility for easier installation, good tensile strength, and inherent corrosion resistance suitable for marine atmospheres.
-
Fire-Survival Core Construction: The Mica Glass Tape layer over XLPE insulation creates a robust, heat-resistant barrier that maintains electrical insulation integrity at extreme temperatures, preventing circuit failure during a fire.
-
Durable External Protection: A PVC outer sheath provides essential resistance to abrasion, moisture, oils, and general environmental exposure.
