Product Overview
The CJPJP/NC is a premium, unarmored fire resistant marine cable engineered for safety-critical circuits in protected installations where superior flexibility, enhanced sheath performance, and guaranteed circuit integrity are paramount. It combines the essential Mica Glass Tape + XLPE fire-survival insulation (IEC 60331) with a high-performance Cross-linked Polyolefin (SHF2) inner sheath, offering better thermal and mechanical resistance than standard sheaths. This flexible, lightweight design is ideal for routing in cable trays, conduits, and enclosed spaces, providing life-safety systems with reliable operation during a fire while ensuring low smoke and zero halogen emission.
Key Features & Benefits
-
Certified Fire Resistance (IEC 60331): Ensures that vital emergency and essential circuits (e.g., emergency lighting, fire alarms, communication systems) remain operational for a specified duration under fire conditions, which is crucial for life safety and evacuation procedures.
-
Enhanced Sheath Durability (SHF2): Features a Cross-linked Polyolefin (SHF2) inner sheath, which provides superior long-term resistance to high temperatures, deformation, cracking, and environmental stress compared to standard thermoplastic materials.
-
Superior Flexibility & Lightweight: The unarmored (no metallic armor) construction ensures excellent flexibility, ease of handling, and reduced weight, facilitating faster and simpler installation in cable management systems.
-
Fire-Survival Core Technology: The Mica Glass Tape layer over XLPE insulation forms a robust ceramic barrier under intense heat, maintaining electrical insulation integrity and preventing circuit failure during a fire event.
-
Advanced Fire Safety (LSZH): Complies with IEC 60754 (Halogen Free) and IEC 61034 (Low Smoke), drastically reducing the emission of corrosive/toxic gases and smoke density to facilitate safer evacuation and protect sensitive equipment.
