Product Overview
The CHEF/NA is a core, unarmored Fire Resistant marine communication cable designed for essential circuits where maintaining signal integrity during a fire is paramount, and installation requires a lightweight, flexible solution. It features the critical Mica/EPR insulation system to meet IEC 60331 fire resistance standards, protected by a durable PCP (Polychloroprene) outer sheath. This cable provides a reliable and cost-effective option for vital alarm and control systems within protected cable routes in marine and industrial settings.
Key Features & Benefits
-
Certified Fire Survival: Complies with IEC 60331, ensuring the cable continues to function for critical alarm and control circuits during a fire emergency.
-
Robust & Flexible Protection: The PCP (Polychloroprene) Sheath offers excellent resistance to oil, weathering, abrasion, and mechanical stress, while maintaining good flexibility for easier installation in tight spaces.
-
Lightweight & Economical: The unarmored, single-sheath design results in a lighter weight and more economical cable compared to armored variants, ideal for fixed installations within conduit, trunking, or protected areas.
-
Marine & Industrial Durability: Built to IEC 60092 standards, it is suitable for the environmental challenges found on ships, offshore platforms, and in plants like power generation and chemical processing.
