What Is Oil-immersed Transformer？

Oil transformer is a common type of power transformer. It uses insulating oil to cool and insulate the internal components of the transformer.

 

Oil-immersed transformers consist of two or more coils (primary and secondary windings) and an iron core. These coils and cores are soaked in insulating oil to maintain their cooling and insulating properties.

 

Insulating oil plays an important role in oil-immersed transformers. It not only effectively cools the internal components of the transformer, but also provides insulation protection from arcing and discharge. At the same time, insulating oil also has good electrical insulation performance and stability, and can work stably for a long time in high temperature environments.

Three Phase Oil Immersed Transformer

Oil-immersed transformers are widely used in power transmission and distribution systems, industrial equipment, construction and other fields. They are often used to transform and regulate voltage to suit the needs of different power systems. The capacity of oil-immersed transformers ranges from a few kilowatts to hundreds of megawatts, and the specific specifications and models are determined according to actual needs.
