Product Overview
The CJVR92/NA is a heavy-duty, fire-resistant marine flexible power cable engineered for the most critical and physically demanding safety circuits. It provides certified fire survival alongside maximum mechanical protection through a construction that combines a fire-resistant mica/XLPE insulation core, a complete dual-layer PVC sheath system, and galvanized steel wire armor. This cable is designed to ensure circuit integrity during a fire while withstanding harsh environmental and physical stresses, making it ideal for essential emergency systems in exposed or high-risk areas.

Key Performance Characteristics
-
Certified Fire Resistance (IEC 60331): The mica glass tape and XLPE insulation system is engineered to maintain circuit integrity and continue operating for a specified duration under direct flame, a critical requirement for all life-safety and emergency power circuits.
-
Complete Mechanical & Environmental Protection: Features a full dual-sheath system (inner and outer) made of PVC. The outer sheath provides an additional, robust layer of protection for the galvanized steel wire armor against abrasion, impact, moisture, oils, and chemicals, ensuring long-term durability.
-
Superior Armor Protection: The galvanized steel wire braid armor offers the highest level of resistance to crushing, impact, and tensile stresses, physically safeguarding the critical fire-resistant core in the most demanding installations.
-
Flame Retardant: Complies with IEC 60332-1 and IEC 60332-3-22, inhibiting the spread of flame along the cable run.
Standards & Compliance
This cable is designed and manufactured in compliance with key international marine and fire safety standards:
-
IEC 60092-350, 353 (General construction and armor)
-
IEC 60228 (Conductors)
-
IEC 60092-360 (Insulation and sheath)
-
IEC 60331 (Fire Resistance)
-
IEC 60332-1 & IEC 60332-3-22 (Flame retardancy)
Typical Applications
This fully protected, armored cable is specified for the most critical safety circuits where fire survival and maximum physical durability are non-negotiable:
-
Marine & Offshore: Vital power feeds to emergency generators and fire pumps, critical alarm and control circuits, and essential systems on exposed decks, in engine rooms, or other high-risk areas on ships and offshore platforms.
-
Heavy Industry & Critical Infrastructure: Safety-critical wiring in power plants, mining operations, chemical processing facilities, and heavy industrial settings where regulations demand both certified fire-resistant cabling and the highest level of mechanical protection.
