Product Overview
The CKEF80/NA is a high-performance Fire Resistant (IEC 60331) marine control cable engineered for critical circuits that must maintain functionality during a fire event. It utilizes a specialized Mica Glass Tape and EPR Insulation system and is constructed with Low Smoke Halogen Free (LSHF) materials. Designed without an overall outer sheath, it is ideal for protected installations within panels, conduits, or trays on marine vessels and offshore platforms, ensuring safety and circuit integrity in emergencies.
Key Features & Benefits
-
Guaranteed Circuit Integrity: Complies with IEC 60331 Fire Resistance standards, ensuring continued operation of critical power, lighting, and control systems for a specified duration under fire conditions.
-
Comprehensive Safety Design: Combines fire resistance with Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties to minimize hazardous emissions, alongside standard Flame Retardancy (IEC 60332).
-
Robust & Flexible Construction: The Mica/EPR insulation provides excellent thermal stability (90°C) and fire protection. Tinned copper braid armor offers mechanical protection and EMI shielding. The "0" code indicates No Outer Sheath, making it suitable for confined or protected spaces.
