Product Overview
The CJVR90/SA is a robust and flexible marine power cable designed to deliver reliable performance in demanding environments. Combining the flexibility of fine-stranded conductors with the superior mechanical protection of galvanized steel wire armor and a PVC inner sheath, this cable is an ideal choice for power, lighting, and control circuits where high tensile strength and resistance to impact are critical, particularly in exposed or mechanically stressful areas on vessels and offshore installations.

Key Performance Characteristics
-
Superior Mechanical Protection: The galvanized steel wire braid armor provides excellent resistance to crushing, impact, abrasion, and rodent damage, making it suitable for the most physically demanding routing paths.
-
High Flexibility Design: Despite its heavy-duty armor, the cable utilizes fine-stranded (Class 5/6) tinned copper conductors, ensuring it remains sufficiently flexible for installation in complex cable trays and confined spaces.
-
Bunched Flame Retardancy: Rated "SA" for flammability, this cable meets stringent flame retardant standards (IEC 60332-1 & IEC 60332-3-22) when installed in bunched configurations, helping to prevent the spread of fire.
-
Cost-Effective Durability: The PVC inner sheath offers a balance of good mechanical and environmental protection at a practical cost point, complementing the robust steel armor.
-
Corrosion-Resistant Armor: The galvanized coating on the steel wire braid helps protect against corrosion in humid and saline atmospheres.
Standards & Compliance
This flexible cable is designed and manufactured in compliance with key international marine and safety standards:
-
IEC 60092-350, 353 (General construction and tests for shipboard power cables)
-
IEC 60228 (Conductors of insulated cables)
-
IEC 60092-360 (Insulating and sheathing materials)
-
IEC 60332-1 & IEC 60332-3-22 (Tests for flame retardancy)
Typical Applications
This armored flexible cable is engineered for applications where maximum mechanical strength is required:
-
Marine & Offshore: Power feeds and control circuits for deck machinery, in engine rooms, for winches, and on offshore oil & gas platforms where cables are exposed to constant vibration, potential impact, and harsh conditions.
-
Heavy Industrial: Flexible yet heavily protected wiring in mining operations, metallurgical plants, and large-scale industrial machinery where cables must withstand severe mechanical stress and abrasive environments.
