Recent Projects - Medium Voltage (MV) Substations for Ship-to-Shore Cranes

Six OLSUN MV Substations were shipped to the Port of Honolulu where they were installed in massive ship-to-shore cranes that are used to unload containers from ocean vessels to the dock terminal. Each crane requires one 1000kVA transformer and one 300kVA transformer. The transformers are installed in the power service rooms at the top of the cranes so the transformers must be able to operate in adverse weather conditions and must be able to withstand the movements of the crane.
