Product Overview
The CHEPJ90/NC is an advanced Fire Resistant marine-grade communication cable engineered for critical circuits where maintaining operational integrity during a fire is paramount. It features a core construction of Mica glass tape with EPR insulation, Halogen-Free Low Smoke (LSHF) compounds, and Galvanized Steel Wire Braid armor, providing exceptional protection and circuit continuity under extreme conditions. This cable is designed for the most demanding safety applications on ships, offshore platforms, and in high-risk industrial plants, fully complying with IEC 60331 for fire resistance.
Key Features & Benefits
-
Certified Fire Resistance: Meets IEC 60331 standards, ensuring continued circuit functionality during a fire for critical alarm, communication, and control systems.
-
Comprehensive Safety: Combines Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties to minimize toxic fumes and improve visibility, with added Flame Retardant (IEC 60332) performance.
-
Robust Armored Construction: The Galvanized Steel Wire Braid provides excellent mechanical protection and earth continuity. The Cross-linked Polyolefin (SHF2) inner sheath offers thermal and chemical resistance.
-
Optimized for Protected Routing: Designed without an additional outer sheath (Code 0), making it suitable for installation in protected cable trays, conduits, or trunking where maximum internal space and flexibility are required.
