Product Overview
The CHJ82/NA is a Fire Resistant marine communication cable designed to ensure critical signal transmission continues during fire emergencies while providing excellent installation flexibility. It features a fire-survivable mica glass tape + XLPE insulation system, a flexible tinned copper wire braid armor, and a protective PVC outer sheath. Engineered to meet the IEC 60331 standard for fire resistance, this cable is an ideal solution for vital telecommunication and data circuits on vessels, offshore platforms, and in industrial plants where maintaining circuit integrity under fire is required, and where the flexibility of copper armor is beneficial.
Key Features & Benefits
-
Critical Fire Resistance (IEC 60331): The mica glass tape + XLPE insulation (Code J) is designed to maintain circuit integrity and continue operating under direct flame, ensuring emergency communications and control signals remain active.
-
Flexible Armor with EMI Shielding: The tinned copper wire braid armor (Code 8) provides robust mechanical protection while offering superior flexibility for easier installation in confined or complex pathways. It also provides inherent shielding against electromagnetic interference (EMI).
-
Durable & Cost-Effective Sheathing: A tough PVC outer sheath (Code 2) offers reliable resistance to abrasion, moisture, oils, and general environmental wear.
-
Flame Retardant: Complies with Flame Retardant standards (IEC 60332-1 & -3-22) to inhibit the spread of fire along the cable.
