Product Overview
The CHEFP/NA is a specialized Fire Resistant (FR) marine communication cable designed for critical applications where maintaining circuit integrity during a fire is the primary requirement. It features a core of mica glass tape and EPR insulation for fire survival, protected by a durable PCP (Polychloroprene) outer sheath and an overall EMI screen. This cable meets essential fire resistance and flame retardancy standards and is suitable for environments where the specific Low Smoke Halogen Free (LSHF) properties are not mandated but core fire circuit functionality is paramount.
Key Features & Benefits
-
Guaranteed Fire Circuit Integrity: Engineered to meet Fire Resistant standard IEC 60331, ensuring continued operation of vital systems during a fire emergency, with additional Flame Retardant (IEC 60332) properties.
-
Durable & Protective Sheath: The PCP (Polychloroprene) sheath provides excellent resistance to oils, chemicals, weathering, abrasion, and mechanical impact, offering robust protection in harsh marine and industrial environments.
-
Signal Integrity Protection: An overall tinned copper braid or foil screen effectively shields against electromagnetic interference (EMI), ensuring clear signal transmission for sensitive communication and control systems.
-
Note on Safety Characteristics: This “NA” variant is designed and tested for Fire Resistance (IEC 60331). For applications requiring Halogen-Free and Low Smoke emission properties (per IEC 60754 & IEC 61034), please refer to “NC” designated cables in our range.

Applications
This cable is engineered for critical circuits where fire survival is essential, and is commonly used in:
-
Fire-resistant power, control, and communication circuits on ships and offshore platforms where the PCP sheath’s oil and weather resistance is advantageous.
-
Critical industrial instrumentation and control lines in power plants, chemical facilities, and other harsh environments where fire resistance and mechanical durability are required, and specific LSHF criteria may not apply.
