Medium Voltage Marine Cable for Shipboard Feeders
Screened medium-voltage cable for propulsion converters, main generators and shore-to-ship supply, built to IEC 60092-354 with a copper tape or wire screen.
Construction and performance
Medium-voltage cable is specified where the propulsion drive, the main generator or a shore connection operates above 1kV. XLPE insulation carries a higher continuous conductor temperature than EPR, which reduces the cross-section required for a given current, and the metallic screen confines the radial field and provides the earth-fault current path. The construction follows IEC 60092-354, and the screen cross-section is selected from the prospective fault current and the clearing time agreed with the electrical design.
Construction
- Compacted copper or aluminium conductor, class 2
- Semiconductive conductor screen
- XLPE insulation to IEC 60092-351
- Semiconductive insulation screen
- Copper tape or copper wire metallic screen with counter helix
- SHF2 or LSZH oversheath to IEC 60092-359
Applications
- Vessel propulsion feeders
- Marine power-plant outgoing circuits
- High-voltage shore-to-ship supply
- Offshore substation interconnection
