Product Overview
The CHEPJP80/NC is a high-performance Fire Resistant (FR) marine communication cable engineered to maintain critical signal transmission during fire emergencies. It combines a mica glass tape and EPR insulation system with a Low Smoke Halogen Free (LSHF) construction, EMI screening, and flexible copper braid armor. Designed without an outer oversheath for specific installation requirements, it provides essential fire integrity and signal protection for vital circuits in marine, offshore, and hazardous industrial applications.
Key Features & Benefits
-
Core Fire Survival Capability: Certified to Fire Resistant standard IEC 60331, ensuring continued circuit operation during a fire, complemented by Flame Retardant (IEC 60332) properties to inhibit flame propagation.
-
Enhanced Safety Environment: Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) design minimizes the emission of corrosive gases and dense smoke, crucial for safe evacuation and firefighting.
-
Optimal Protection & Flexibility: Features an overall tinned copper braid or foil screen for effective electromagnetic interference (EMI) shielding. The tinned copper wire braid armor (Code 8) provides robust yet flexible mechanical protection and serves as a grounding shield.
-
Compact & Durable Construction: The mica/EPR insulation offers superior thermal and fire-resistant properties. The cross-linked polyolefin (SHF2) inner sheath provides primary environmental protection in a compact design without an outer oversheath.

Applications
This cable is specifically designed for critical systems where fire integrity and EMI protection are paramount, and where a final outer sheath may be provided by the system or is not required:
-
Essential circuits within protected cable trays or conduits on ships and offshore platforms (e.g., emergency communication, fire alarm systems).
-
Critical instrumentation and data lines in control panels or protected runs within power plants, chemical facilities, and mining operations.
