Shore Power - Required Cable Size
Shore-connection cable size for high-voltage ship-shore power per ISO/IEC/IEEE 80005-1 - based on load current and cable derating for parallel runs.
Total line current
306A
Per-set current
153A
Indicative cable size
120 mm²
Formula, assumptions, and limits
HVSC standardised at 6.6 or 11 kV (AC) for most segments. Cruise and container ships typically need 10 MW+. Apply cable derating factors per IEC 60287 for trefoil vs flat formation.
