Oil Immersed Transformer - Oil Cooling System
Oil immersed transformer, also called oil filled transformer, is a kind of voltage transformation device utilizing oil cooling method to reduce the transformer temperature. Different from the dry type transformer, the body of oil immersed transformer is installed in the welded steel oil tank filled with insulation oil. When oil immersed transformer in operation, the heat of coil and iron core firstly is transformed to the insulation oil and then to the cooling medium. And according to the capacity sizes, it can be divided into immersed natural cooling transformer and immersed forced air cooling transformer.
