Product Overview
The CKEPF/NC is an unarmored Fire Resistant marine control cable, providing essential circuit integrity during fire emergencies in installations where mechanical armor is not required. Its construction combines Mica/EPR fire-resistant insulation with a single, robust Halogen-Free, Low Smoke (LSHF) Thermoplastic Polyolefin (SHF1) sheath. This design offers a flexible and lightweight solution for critical power, lighting, and control circuits in marine, offshore, and industrial environments, maintaining full compliance with IEC 60331 for fire resistance and IEC 60092 standards.
Key Features & Benefits
-
Certified Fire Resistance: Complies with IEC 60331, ensuring the cable continues to operate critical circuits for a defined period under direct flame, vital for emergency and safety systems.
-
Lightweight & Flexible: The unarmored design with a single SHF1 sheath reduces weight and improves flexibility, making it easier to install in conduits, trays, or tight spaces where extra mechanical protection is provided by the installation method.
-
Superior Fire Safety: Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties prevent the emission of corrosive gases and reduce smoke density. The cable also meets Flame Retardant standards (IEC 60332).
-
Reliable Core Protection: Mica glass tape with EPR insulation ensures the conductor's integrity and functionality at temperatures up to 90°C during a fire event.

Applications
This cable is specified for fixed installations where fire circuit integrity is required but external mechanical protection is provided by other means (e.g., conduit, protected cable trays):
-
Marine & Offshore: Control, signaling, and low-power circuits within protected panels, consoles, and enclosed cable routes on ships and oil platforms (e.g., internal wiring for control desks, alarm systems).
-
Industrial: Fire-resistant control and instrumentation circuits inside control rooms, enclosures, or protected cable management systems in power plants, chemical facilities, and mining operations.
