Product Overview
The CKEF82/NA is a specialized Fire Resistant (IEC 60331) marine control cable designed for critical circuits where maintaining circuit integrity during a fire is essential. Combining a mica glass tape and EPR insulation system with Low Smoke Halogen Free (LSHF) materials, it ensures both fire survival and enhanced safety for power, lighting, and control systems in high-risk environments such as offshore platforms and ships. It is fully compliant with the IEC 60092 series for marine applications.
Key Features & Benefits
-
Critical Fire Resistance: Meets IEC 60331 standards, ensuring the cable continues to operate for a specified time under direct flame, which is crucial for emergency systems, alarms, and shutdown circuits.
-
Enhanced Safety Suite: Features Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties to reduce toxic fumes and smoke opacity, alongside general Flame Retardancy (IEC 60332-1 & -3-22).
-
Robust Marine Construction: EPR insulation offers thermal stability (90°C) and durability. A tinned copper wire braid armor provides mechanical protection and EMI shielding, with an overall PVC sheath for environmental resistance.
