Product Overview
The CJ85/NC is a compact and high-performance fire resistant marine cable, designed with a streamlined construction that omits a separate inner sheath. It combines a fire-survival core of Mica Glass Tape + XLPE insulation (IEC 60331) with a flexible tinned copper wire braid armor and a robust, high-grade Cross-linked Polyolefin (SHF2) outer sheath. This design delivers certified circuit integrity during a fire, superior long-term sheath durability, and excellent mechanical protection in a more efficient package, ideal for space-constrained or demanding installations in critical marine and industrial environments.
Key Features & Benefits
-
Certified Fire Resistance (IEC 60331): Ensures vital emergency circuits (e.g., emergency lighting, fire alarms, pump controls) maintain operation for a specified duration under fire conditions, which is crucial for life safety and asset protection.
-
Compact & Efficient Structure: The absence of a separate inner sheath results in a more streamlined and potentially lighter cable, optimizing space and material use while maintaining all essential protective functions.
-
High-Performance Outer Sheath (SHF2): The Cross-linked Polyolefin (SHF2) outer sheath provides exceptional resistance to high temperatures, deformation, cracking, chemicals, and abrasion, far exceeding the performance of standard thermoplastic sheaths.
-
Flexible & Corrosion-Resistant Armor: A braid of tinned copper wires offers excellent flexibility for installation, ease of termination, and reliable corrosion resistance in marine and humid environments.
-
Enhanced Fire Safety (LSZH): As an NC-grade cable, it is Halogen Free and Low Smoke, minimizing corrosive gas emission and smoke density to facilitate safer evacuation and protect equipment.
