Product Overview
The CHJP92/NA is a Fire Resistant marine communication cable designed to maintain critical telecommunication and data circuit integrity during fire emergencies. It features a fire-survivable mica glass tape + XLPE insulation system, an overall electromagnetic screen, heavy-duty galvanized steel wire armor, and a protective PVC outer sheath. Engineered to meet the stringent IEC 60331 standard for fire resistance, this cable is built for essential communication and control systems on vessels, offshore platforms, and in industrial plants where maintaining signal transmission under fire conditions is paramount.
Key Features & Benefits
-
Critical Fire Resistance (IEC 60331): The core mica glass tape + XLPE insulation (Code J) is engineered to maintain circuit integrity and continue operating for a specified duration under direct flame, a critical requirement for emergency and safety systems.
-
Robust Mechanical & EMI Protection: The galvanized steel wire braid armor (Code 9) provides maximum protection against impact and crushing. The integrated overall screen (Code P) shields against electromagnetic interference (EMI) for clear signal transmission.
-
Durable Outer Protection: A tough PVC outer sheath (Code 2) offers reliable resistance to abrasion, moisture, oils, and general environmental wear, ensuring long-term durability.
-
Flame Retardant: Complies with Flame Retardant standards (IEC 60332-1 & -3-22) to inhibit the spread of fire along the cable.
