Product Overview
The CHEF90/NA is a premium Fire Resistant (FR) marine communication cable engineered for critical circuits that must maintain circuit integrity during a fire. It combines EPR insulation with a Mica Glass Tape barrier, PCP inner sheath, and Galvanized Steel Wire Armor to provide exceptional fire performance and mechanical durability. Compliant with the stringent IEC 60331 standard for fire resistance, it is designed for use in marine, offshore, and high-risk industrial safety systems.
Key Features & Benefits
-
Certified Fire Resistance: Engineered to meet IEC 60331 requirements, ensuring continued operation of essential communication and safety systems during a fire emergency.
