What is the purpose of oil in a transformer? - Electrical spain transformer tank oil technology

Transformer oil absorbs this heat from the windings and conducts it to the outside of the transformer, where it can be dissipated to the outside air. It is possible to build an air-cooled transformer. These are used where spillage of the insulating oil is an un-acceptable hazard. I.e. for indoor substations, where the oil would be a fire hazard.Why Conservator Used in Transformer? Electrical ConceptsJan 08, 2019A conservator tank of transformer provides adequate space to this expanded transformer oil. It also acts as a reservoir for transformer insulating oil. When volume of transformer insulating oil increases due to load and ambient temperature, the vacant space above the oil level inside the conservator is partially occupied by the expanded oil.
