Product Overview
The CHJ85/NC is a premium Fire Resistant, Low Smoke Halogen Free (LSHF) marine communication cable designed for mission-critical systems where maintaining signal integrity during a fire is paramount, coupled with a need for high flexibility. It features a fire-survivable mica glass tape + XLPE insulation system, a highly flexible tinned copper wire braid armor, and a high-performance cross-linked polyolefin (SHF2) outer sheath. This cable is engineered 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 when needed most.
-
Enhanced Personnel & Environmental Safety (LSHF/NC Grade): Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) construction drastically reduces the emission of toxic, corrosive gases and smoke, promoting safer evacuation and firefighting in confined spaces. The cable is also Flame Retardant (IEC 60332).
-
Superior Flexibility & EMI Shielding: The tinned copper wire braid armor (Code 8) provides excellent mechanical protection while offering exceptional flexibility, simplifying installation in complex or space-constrained routes. It also provides inherent shielding against electromagnetic interference (EMI).
-
High-Performance, Durable Sheath: The cross-linked polyolefin (SHF2) sheath (Code 5) offers exceptional thermal stability, chemical resistance, and mechanical toughness, providing superior long-term external protection compared to standard thermoplastics.
