Product Overview
The CKEV80/NA is a specialized, single-sheathed Fire Resistant marine control cable, engineered to maintain critical circuit integrity during fire emergencies. Featuring a robust Mica Glass Tape + EPR insulation core, it complies with the stringent IEC 60331 fire resistance standard. This design, without an additional outer sheath, is optimized for installations where space, weight, or specific containment systems are considerations, while still providing essential protection for vital power, lighting, and control circuits on ships, offshore platforms, and in hazardous industrial plants. It also incorporates Low Smoke Halogen Free (LSHF) properties for personnel safety.
Key Features & Benefits
-
Certified Fire Resistance: Complies with IEC 60331, ensuring continued operation of emergency circuits (e.g., alarms, shutdown systems) for a defined period under direct flame impingement.
-
Enhanced Fire & Safety Profile: Combines critical fire resistance with Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties to minimize toxic and corrosive fumes, facilitating safer evacuation.
-
Flame Retardant Construction: Meets IEC 60332-1 & -3-22 flame retardancy standards to inhibit the spread of fire along the cable.
-
Robust Core Protection: The Mica/EPR composite insulation ensures superior thermal and dielectric stability at high temperatures. Tinned copper braid armor provides mechanical protection, EMI shielding, and serves as the primary protective layer.
