Product Overview
The CJVP82/SA is a robust and cost-effective double-sheathed marine power cable designed for applications requiring enhanced mechanical protection and environmental sealing alongside standard flame retardancy. It features reliable XLPE insulation, a collective copper screen for EMI protection, and a flexible braided armor of tinned copper wires. Its distinguishing feature is the dual-layer PVC sheath, which provides excellent resistance to abrasion, impact, oils, and moisture, making it a durable choice for demanding fixed installations in marine and industrial environments where halogen-free materials are not specifically required.
Key Features & Benefits
-
Dual-Sheath Mechanical Protection: Features both an inner and a robust outer sheath made of Polyvinyl Chloride (PVC), offering superior resistance to abrasion, crushing, and harsh environmental conditions compared to single-sheathed designs.
-
Flexible & Corrosion-Resistant Armor: The braided armor of tinned copper wires provides excellent flexibility for easier installation and routing, along with inherent corrosion resistance suitable for marine atmospheres.
-
Standard Flame Retardancy: Complies with IEC flame retardant standards (SA grade) for bunched cables, helping to prevent the spread of flame along cable runs.
-
Stable Electrical Performance: XLPE (Cross-Linked Polyethylene) insulation ensures high dielectric strength and thermal stability for continuous operation at temperatures up to 90°C.
-
Effective EMI Shielding: The integrated collective copper screen protects against electromagnetic interference, ensuring signal integrity for power and control systems.

Standards & Approvals
This cable is designed and manufactured in accordance with the following international standards:
-
IEC 60092-350, 353: Electrical installations in ships – General construction and test methods.
-
IEC 60228: Conductors of insulated cables.
-
IEC 60092-360: Insulating and sheathing materials.
-
IEC 60332-1: Test for vertical flame propagation for a single wire/cable.
-
IEC 60332-3-22: Test for vertical flame spread of bunched cables – Category A.
Typical Applications
-
Marine & Offshore: Power, lighting, and control systems on ships, workboats, and in certain areas of offshore installations where enhanced mechanical protection from double sheathing is needed, and the use of PVC is permitted.
-
General Industrial: Robust power distribution in factories, plants, mining operations, and infrastructure projects where cables may be exposed to physical damage, moisture, or oils, and standard flame-retardant properties are sufficient.
