What's the Oil - Immersed Transformer?
Oil – immersed transformer is a kind of voltage conversion device which uses oil – cooled way to reduce transformer temperature. Unlike dry transformers, the body of oil-immersed transformers is mounted in a welded steel tank filled with insulating oil. When the oil-immersed transformer is in operation, the heat of the coil and core is first converted into insulating oil, and then into the cooling medium. And according to the capacity size, it can be divided into immersed natural cooling transformer and immersed forced air cooling transformer.
