Product Overview
The CHJ96/NC is a Fire Resistant, Low Smoke Halogen Free (LSHF) marine communication cable engineered to maintain critical signal transmission during fire emergencies. It features a specialized mica glass tape + XLPE insulation system designed for circuit integrity under fire, heavy-duty galvanized steel wire armor for mechanical protection, and a LSHF thermoplastic polyolefin (SHF1) outer sheath. This cable is essential for ensuring the continuous operation of vital telecommunication and data systems on ships, offshore platforms, and in industrial plants, fully complying with IEC 60092 standards and the fire resistance requirement of IEC 60331.
Key Features & Benefits
-
Guaranteed Fire Survival & Circuit Integrity: The mica glass tape + XLPE insulation (Code J) is engineered to maintain circuit operation during a fire (IEC 60331), ensuring that emergency communications, alarms, and control signals remain functional in critical situations.
-
Enhanced Personnel Safety (LSHF/NC Grade): Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) construction minimizes the emission of toxic, corrosive fumes and reduces smoke density, facilitating safer evacuation and firefighting in confined spaces. It is also Flame Retardant (IEC 60332).
-
Maximum Mechanical Protection: The galvanized steel wire braid armor (Code 9) provides superior resistance against impact, crushing, and mechanical damage, ideal for exposed or high-risk installation areas.
-
Durable & Safe Sheathing: The Thermoplastic Polyolefin (SHF1) sheath (Code 6) provides robust environmental protection while maintaining the cable's LSHF safety properties.
