Water cooled transformers


This type of transformers has a special water cooling system which is in addition to natural air cooling system. In indirect water-cooled transformers between windings is placed the insulated cooler. This cooler is made of copper pipe with a diameter which ensures adequate flow of cooling medium. Such a solution with high efficiency cooling factor helps to reduce the size of the transformer and allows to evacuate the heat losses outside of the swichtbox.
