Product Overview
The CHJ95/NC is a premium Fire Resistant, Low Smoke Halogen Free (LSHF) marine communication cable engineered for mission-critical systems where maintaining signal integrity during a fire is essential. It features a specialized mica glass tape + XLPE insulation system for circuit survival under fire, heavy-duty galvanized steel wire armor for mechanical protection, and a high-performance cross-linked polyolefin (SHF2) outer sheath. This cable is designed to ensure the continuous operation of vital telecommunication, data, and control systems in the most demanding marine, offshore, and industrial environments, meeting IEC 60092 standards and the stringent IEC 60331 fire resistance requirement.
Key Features & Benefits
-
Assured Fire Survival (IEC 60331): The mica glass tape + XLPE insulation (Code J) is designed to maintain circuit integrity and functionality during a fire, ensuring emergency communications and critical data links remain operational.
-
Enhanced Safety (LSHF/NC Grade): Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties minimize toxic fume emission and smoke opacity, promoting safer evacuation. The cable is also Flame Retardant (IEC 60332) to inhibit fire spread.
-
Superior Mechanical & Environmental Protection: The galvanized steel wire braid armor (Code 9) provides maximum defense against impact and crushing. The cross-linked polyolefin (SHF2) sheath (Code 5) offers exceptional thermal stability, chemical resistance, and durability.
-
Reliable Performance: Rated for continuous operation at 90°C, ensuring stable performance in high-temperature environments.
