Product Overview
The CHJ92/NA is a robust Fire Resistant marine communication cable designed to ensure the continued operation of critical systems during fire emergencies. It features a fire-survivable mica glass tape + XLPE insulation system, heavy-duty galvanized steel wire armor, and a protective PVC outer sheath. Engineered to meet the IEC 60331 standard for fire resistance, this cable is essential for maintaining vital telecommunication, data, and control signal integrity on vessels, offshore platforms, and in industrial plants where circuit survival under fire conditions is a critical requirement.
Key Features & Benefits
-
Critical Fire Resistance (IEC 60331): The mica glass tape + XLPE insulation (Code J) is specifically designed to maintain circuit integrity and continue operating under direct flame, ensuring that emergency communications, alarms, and control signals remain active.
-
Maximum Mechanical Protection: The galvanized steel wire braid armor (Code 9) provides superior resistance against impact, crushing, and physical damage, making it suitable for exposed or high-risk installation areas.
-
Durable & Cost-Effective Sheathing: A tough PVC outer sheath (Code 2) offers reliable protection against abrasion, moisture, oils, and general environmental factors, 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.
