Product Overview
The CHEPF/NC is a Non-Armored, Fire Resistant marine communication cable that provides essential circuit integrity during fire emergencies. It combines Mica/EPR insulation certified to IEC 60331 with Low Smoke Halogen Free (LSHF) safety characteristics. Designed for fixed installations where mechanical protection is provided by the routing path (conduits, trays, or protected zones), this lighter and more cost-effective cable offers a streamlined solution for fire-resistant communication and control circuits on vessels, offshore platforms, and in industrial plants.
Key Features & Benefits
-
Certified Fire Resistance: Complies with IEC 60331, ensuring critical signals and power are maintained during a fire to support emergency systems and safe shutdown procedures.
-
Enhanced Personnel & Environmental Safety: Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties minimize the release of corrosive gases and opaque smoke, protecting escape routes and equipment.
-
Dual Fire Performance: Integrates core Fire Resistant capability with overall Flame Retardant (IEC 60332-1 & -3-22) properties to prevent flame propagation along the cable.
-
Lightweight & Flexible Design: The Non-Armored construction makes the cable lighter, more flexible, and easier to install in conduits, cable trays, or tight spaces where external protection is otherwise assured.
-
Reliable Core Protection: Mica glass tape with EPR insulation provides the fundamental fire integrity, jacketed by a durable Thermoplastic Polyolefin (SHF1) outer sheath for general environmental protection.

Applications
This non-armored, fire-resistant cable is designed for fixed, protected installations within:
-
Critical alarm, telecommunication, instrumentation, and data systems on marine vessels and offshore constructions (e.g., oil & gas platforms), routed inside protected conduits or trays.
-
Essential control and signaling circuits in power plants, chemical facilities, and mining operations where fire circuit integrity is required but external mechanical protection is provided by the installation method.
