Product Overview
The CKEPJ/NC is a specialized unarmored Fire Resistant marine control cable designed for critical circuits where both circuit integrity during a fire and enhanced personnel safety are paramount. It combines IEC 60331 fire resistance with Halogen-Free, Low Smoke (LSHF) properties in a compact, flexible design. Featuring a robust Mica Glass Tape + EPR insulation core and a single-layer Cross-linked Polyolefin (SHF2) sheath, this cable is engineered to ensure the continuous operation of emergency systems while minimizing toxic hazards, making it ideal for confined spaces and general fixed installations on vessels, offshore platforms, and in hazardous industrial plants.
Key Features & Benefits
-
Certified Fire Resistance: Complies with IEC 60331, ensuring the cable maintains circuit integrity and continues to function for a specified period under direct fire exposure, which is critical for emergency lighting, alarms, and shutdown circuits.
-
Enhanced Safety in Fire: Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties significantly reduce the emission of corrosive, toxic fumes and smoke density, protecting equipment and aiding safe evacuation.
-
Flame Retardant & Robust Sheath: Meets IEC 60332 flame retardancy standards. The Cross-linked Polyolefin (SHF2) sheath offers excellent thermal stability, chemical resistance, and durability without the need for metallic armor, resulting in a lighter and more flexible cable.
-
Reliable Core Insulation: The Mica/EPR composite insulation provides superior electrical and thermal protection at high temperatures, ensuring signal and power integrity in extreme conditions.
