Product Overview
The CHEPJ/SC is a standard, unscreened marine communication cable designed for general-purpose applications where enhanced fire safety is paramount. It features reliable EPR insulation and a durable Cross-linked Polyolefin (SHF2) sheath, delivering full Low Smoke Halogen Free (LSHF) Flame Retardant performance. This cable provides a safe, cost-effective, and environmentally responsible solution for internal shipboard wiring and industrial control circuits where EMI shielding and mechanical armor are not required.
Key Features & Benefits
-
Superior Fire Safety: Certified Halogen-Free (IEC 60754) and Low Smoke (IEC 61034), minimizing the emission of corrosive, toxic gases and smoke density in the event of a fire. Complies with IEC 60332 flame retardancy standards for general and bunched installations.
-
Durable & Resilient Sheathing: The Cross-linked Polyolefin (SHF2) sheath (PJ) offers excellent mechanical toughness, chemical resistance, and longevity, outperforming standard thermoplastic sheaths in harsh conditions while maintaining LSHF properties.
-
Lightweight & Flexible: The unarmored and unscreened design makes this cable lighter and more flexible than shielded or armored variants, simplifying handling and installation in cable trays, conduits, and behind panels.
-
Environmental & Personnel Safety: Ideal for confined spaces and areas with high personnel occupancy, as its LSHF properties significantly improve evacuation conditions and reduce equipment corrosion during a fire incident.

Applications
This general-purpose LSHF cable is designed for safety-critical but non-EMI-sensitive circuits:
-
Marine & Offshore: Internal telecommunication, general alarm systems, and non-critical instrumentation wiring in accommodation areas, control rooms, public spaces, and escape routes on ships and offshore platforms where LSHF regulations apply.
-
Industrial & Public Infrastructure: General data transmission, signaling, and control circuits in power plants, commercial buildings, metro stations, and tunnels where low smoke, zero halogen materials are mandated by safety codes for improved fire safety.
