Product Overview
The CHJPJP/NC is a premium Fire Resistant, Low Smoke Halogen Free (LSHF) marine communication cable designed to ensure uninterrupted operation of critical systems during fire emergencies, while prioritizing personnel safety and signal integrity. It features a fire-survivable mica glass tape + XLPE insulation system, an overall electromagnetic screen, and a high-performance cross-linked polyolefin (SHF2) outer sheath. This non-armored, flexible cable offers an optimal combination of circuit integrity under fire (IEC 60331), enhanced environmental safety (LSHF), and EMI protection for vital telecommunication and data networks in marine, offshore, and industrial applications.
Key Features & Benefits
-
Guaranteed Fire Survival & Circuit Integrity (IEC 60331): The mica glass tape + XLPE insulation (Code J) is engineered to maintain circuit operation during a fire, ensuring emergency communications, alarms, and control signals remain active when needed most.
-
Enhanced Personnel Safety (LSHF/NC Grade): Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties drastically reduce the emission of toxic, corrosive gases and smoke density, facilitating safer evacuation and firefighting in confined spaces.
-
Superior EMI/RFI Shielding & Durability: The integrated overall screen (Code P) provides excellent protection against electromagnetic interference. The cross-linked polyolefin (SHF2) sheath (Code PJ) offers exceptional thermal stability, chemical resistance, and mechanical toughness for long-term reliability.
-
Flame Retardant & Flexible: Certified Flame Retardant (IEC 60332). The non-armored design with a flexible SHF2 sheath allows for easier installation in conduits, trays, and confined spaces.
