This technical solution is particularly suitable for applications involving high currents or where the space is limited. The conductor may be cooled internally with a liquid refrigerant (direct cooling) or simply pass through cooling plates in contact with the conductor (indirect cooling), where the liquid is made to circulate (indirect cooling).
This type of cooling system allows heat to be dissipated away from the points of installation and has the advantage of providing compact solutions in protected enclosures, despite the high concentration of power involved. Hitachi Energy can manufacture water-cooled transformers and inductors handling up to 50kA.
