Product Overview
The CHJV92/NA is a robust Fire Resistant marine communication cable engineered for critical applications where maintaining circuit integrity during a fire and providing heavy-duty mechanical protection are essential. It features a fire-survivable mica glass tape + XLPE insulation core, a PVC inner sheath, a galvanized steel wire braid armor, and a final PVC outer sheath. This durable, double-sheathed armored construction is designed to ensure continuous operation of vital telecommunication, instrumentation, and data signals in fire emergencies (IEC 60331) while withstanding harsh physical environments on ships, offshore platforms, and in heavy industry.
Key Features & Benefits
-
Guaranteed Fire Survival (IEC 60331): The mica glass tape + XLPE insulation (Code J) maintains circuit integrity under fire, ensuring emergency and control signals remain functional.
-
Superior Mechanical & Crush Protection: The galvanized steel wire braid armor (Code 9) provides maximum resistance against impact, crushing, and mechanical damage.
-
Robust Environmental Sealing: The double-layer PVC sheath system (Inner V & Outer 2) offers excellent protection against abrasion, moisture, oils, and general environmental stress.
-
Flame Retardant: Complies with Flame Retardant standards (IEC 60332-1 & -3-22) to inhibit the spread of fire.
