Transformer Oil

Transformer oils are used as insulating and protective media in transformers and electrical switches. The main functions of transformer oils are to insulate or prevent the flow of electric current between the energized elements of transformers and electrical switches, to cool or remove heat from the energized parts of the equipment, and to protect the metallic parts of the equipment from the corrosive action of water as well as any other element that might be present in the asset. Transformer oil complies with the international ASTM D-3487 standard.
