Product Overview
The CHEF92/NA is a premium Fire Resistant marine-grade communication cable, engineered to maintain circuit integrity and ensure continuous operation of critical systems during a fire. It combines Mica Glass Tape and EPR insulation for superior fire resistance, alongside Low Smoke Halogen Free (LSHF) properties. Designed to meet the stringent safety and performance requirements of marine, offshore, and heavy industrial applications, this cable is fully compliant with the IEC 60092 series and key fire safety standards.
Key Features & Benefits
-
Superior Fire Resistance: Complies with IEC 60331, ensuring the cable continues to function for a specified period under fire conditions, which is critical for alarm, communication, and safety systems.
-
Enhanced Fire Safety: Features Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties to minimize toxic fumes and smoke opacity, alongside high Flame Retardancy (IEC 60332-1 & -3-22).
-
Robust Construction: The Mica Glass Tape + EPR insulation provides excellent thermal and electrical integrity under extreme heat. Galvanized Steel Wire Braid armor offers superior mechanical protection and grounding.
-
Marine & Industrial Durability: Built with materials like PCP inner sheath and PVC outer sheath to withstand harsh environmental conditions, including moisture, oil, and mechanical stress.
