View MoreProduct Overview Rated voltage 1.8/3kV and below XLPE-insulated marine power cable is a core cable designed for power systems on various vessels, offshore oil platforms, and other marine structures. Using XLPE as insulation material, it provides a higher heat rating (long-term operating temperature up to 90°C), stronger electrical performance, and excellent mechanical strength compared to traditional PVC insulation. For complex marine operating environments, the product range includes flame-retardant (NA/SA/DA type), low-smoke halogen-free low-toxicity (NC/SC type), and variable frequency drive-specific structures, effectively resisting salt spray, oil, moisture, and severe vibration to ensure safe power supply for vessels and offshore operations.
Implementation Standards
- IEC 60092-353:2016: Ships and marine technology — 1kV and 3kV single and multi-core non-radial field extruded solid insulated power cables
- IEC 60332: Cable combustion tests (flame-retardant performance)
- IEC 60754 / IEC 61034: Halogen-free, low-smoke, low-toxicity tests (for SC/NC type)
- GB/T 3956: Cable conductor structure and DC resistance
Model Code Meanings
- C: Marine (series code)
- J: XLPE insulation; V: PVC sheath; P: LSZH polyolefin sheath; F: Chloroprene or thermoset sheath
- Structure codes: 80/82/92 (unarmored or wire braid armored); 85/86/95/96 (with metal wire shielding/armoring)
- R: Flexible conductor; BP: Variable frequency drive structure
Specifications
Using high-quality tinned or annealed copper wire:
- 1-core: 1.0 to 630 mm²
- 2-core: 1.0 to 120 mm²
- 3-core: 1.0 to 240 mm²
- 4-core: 1.0 to 150 mm²
- 5-core: 1.0 to 120 mm²
- Multi-core control type: (7~37) cores x (1~2.5) mm²
- BP variable frequency: e.g., 3x(16~240) + 3x(4~95) mm²
Core Technical Parameters
- Rated voltage (U0/U): 0.6/1kV and 1.8/3kV
- Max long-term conductor temperature: 90°C
- Short-circuit temperature (<=5s): 250°C
- Min bending radius: OD <= 25mm: 4D; OD > 25mm: 6D
Cable Structure
- Conductor: Class 2 stranded or Class 5 flexible, tinned copper wire for marine salt spray resistance
- Insulation: XLPE — excellent stability under harsh thermal cycling
- Metal shielding/armoring: Stainless steel, copper, or aluminum wire braid (codes 82, 85 etc.) for mechanical protection and EMC
- Environmental sheath: SC/NC types use special LSZH polyolefin; fire-resistant models (NH) available
Application Areas
- Power transmission: Main distribution system, propulsion motors, auxiliary power equipment
- Marine engineering: Offshore drilling platforms, FPSOs
- Variable frequency systems: Ship HVAC, pump VFD control
- Emergency circuits: Fire pumps, emergency lighting, alarm systems (fire-resistant type recommended)
Selection Notes
- Engine rooms with oil/fuel: Prefer PVC (V) or chloroprene sheath for oil resistance
- Personnel areas and bridge: SC type LSZH mandatory
- VFD connections: BP series for symmetric core arrangement and metal shield to suppress high-frequency interference
- Tinned copper wire braid armoring recommended for severe salt spray areas
