Offshore High Voltage Station - Heinen & Hopman is very important to assure continuous operation of the Offshore High Voltage Station (OHVS). The OHVS is packed with electrical equipment, like transformers, GIS and switchgears, LV- & HV-switchboards, which generate significant amounts of heat. To prevent overheating and electrical failure this heat needs to be dissipated.
