High-voltage direct current - Wikipedia high-voltage, direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for the bulk transmission of electrical power, in contrast with the more common alternating current (AC) systems. For long-distance transmission, HVDC systems may be less expensive and have lower electrical losses.[email protected]

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.
