Product Overview
The CKEF92/NA is a premium Armored Fire Resistant marine control cable, engineered to provide both exceptional mechanical protection and guaranteed circuit integrity during fire emergencies. It combines Mica Glass Tape and EPR Insulation for fire resistance, a Galvanized Steel Wire Braid Armor for toughness, and Low Smoke Halogen Free (LSHF) materials for safety. This cable is designed for the most critical power, lighting, and control circuits in harsh marine, offshore, and industrial environments where impact resistance and fire survival are mandatory.
Key Features & Benefits
-
Guaranteed Fire Resistance: Complies with IEC 60331, ensuring critical circuits continue to operate under direct flame exposure, which is essential for emergency lighting, alarm, and shutdown systems.
-
Superior Mechanical Protection: The Galvanized Steel Wire Braid Armor (Code 9) provides robust defense against crushing, impact, and mechanical stress, suitable for exposed or high-risk installation areas.
-
Enhanced Fire Safety: Features Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties to minimize toxic fumes and smoke. Also meets general Flame Retardant standards (IEC 60332).
-
Robust Environmental Protection: The dual-layer sheath system—PCP inner sheath for oil/weather resistance and a PVC outer sheath—ensures long-term durability in harsh conditions.
-
High-Temperature Performance: EPR insulation with mica tape allows for a continuous operating temperature of 90°C.
