Advantages and disadvantages of oil-immersed transformers

Advantage

1, transformer oil insulation performance is good, good thermal conductivity, while transformer oil is cheap.

2, can solve the transformer large capacity heat dissipation problem and high voltage insulation problem.

Shortcoming

1. Transformer oil is flammable and may burn and explode when it encounters flames

2, transformer oil is harmful to human body

3, transformer oil needs to be checked regularly

4, oil-immersed transformer seal performance is poor and should be aging, serious leakage of oil in the operation site, affecting the safe operation of equipment, while affecting the environment

5, oil-immersed transformer insulation grade is low, according to A class insulation design, manufacturing
