Product Overview
The CJVP90/SA is a heavy-duty marine power cable engineered for applications demanding maximum mechanical protection and reliable EMI shielding, paired with cost-effective PVC sheathing. It features durable XLPE insulation, a PVC inner sheath, and a collective copper screen. Its defining characteristic is a robust galvanized steel wire braid armor, providing exceptional tensile strength and crush resistance for the most challenging installations. Designed without an outer sheath, this cable is ideal for fixed routes where superior mechanical durability and standard flame-retardant properties are prioritized over halogen-free requirements.
Key Features & Benefits
-
High-Strength Steel Armor: A braided armor of galvanized steel wires delivers superior protection against crushing, impact, and pulling forces, making it suitable for exposed or high-risk mechanical environments.
-
Cost-Effective & Durable Sheathing: Utilizes a proven PVC inner sheath, offering good resistance to abrasion, moisture, and oils, providing reliable protection at a competitive price point.
-
Standard Flame Retardancy: Complies with IEC flame retardant standards (SA grade) for bunched cables, helping to inhibit flame spread along cable runs under defined test conditions.
-
Stable Electrical Performance: XLPE (Cross-Linked Polyethylene) insulation ensures excellent dielectric properties and thermal endurance for continuous operation at 90°C.
-
Effective EMI Protection: The collective copper screen safeguards power and control signals from electromagnetic interference (EMI).

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.
