Product Overview
The CKEF90/NA is a specialized Armored Fire Resistant marine control cable designed for applications requiring robust mechanical protection and guaranteed circuit integrity during fire emergencies. Its defining feature is the exposed Galvanized Steel Wire Braid Armor (without an outer sheath), which allows for direct grounding and efficient installation in specific configurations. Combining Mica Glass Tape and EPR Insulation for fire resistance with Low Smoke Halogen Free (LSHF) safety properties, this cable is ideal for critical control circuits in marine, offshore, and industrial settings.
Key Features & Benefits
-
Guaranteed Fire Resistance (IEC 60331): Ensures critical power, lighting, and control circuits remain operational under direct fire exposure, essential for emergency systems.
-
Exposed Steel Wire Armor: The Galvanized Steel Wire Braid Armor (Code 9) is the outermost layer, providing superior mechanical protection against impact and crushing. This design facilitates effective grounding and can be suitable for certain tray or conduit installations.
-
Enhanced Fire Safety: Constructed with Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) materials, reducing toxic gas emission and smoke density. Also compliant with Flame Retardant standards (IEC 60332).
-
Durable Construction: Features a PCP (Polychloroprene) inner sheath offering resistance to oil, weathering, and abrasion, protecting the core beneath the armor.
-
High-Temperature Capability: EPR insulation ensures stable performance at a continuous operating temperature of up to 90°C.
