1. Insulation

The first function of oil immersed transformer oil is insulation. The insulation strength of transformer oil is much higher than that of air.

The insulation material immersed in oil can not only improve the insulation strength, but also be free from the erosion of moisture.

2. Heat dissipation

The second function of power transformer oil is heat dissipation.

Transformer oil has high specific heat and can be used as coolant.

The heat generated during the operation of the transformer can make the oil near the iron core and winding expand and rise. Through the up and down convection of the oil, the heat is dissipated through the radiator to ensure the normal operation of the transformer.

3. Arc suppression

The third function of transformer oil is arc suppression.

On the on load voltage regulating switch of oil circuit breaker and transformer, arc will be generated during contact switching.

Transformer oil has good thermal conductivity. Under the high temperature of the arc, it will decompose a large amount of gas and produce large pressure, which improves the arc extinguishing performance of the medium and extinguishes the arc quickly.
