Advantages
1. The transformer oil has good insulation performance and good thermal conductivity, and the transformer oil is cheap.
2. It can solve the problem of large-capacity heat dissipation of transformers and high-voltage insulation.
Disadvantages
1. Transformer oil is flammable and may burn when it encounters flames
2. Transformer oil is harmful to human body
3. Transformer oil needs regular inspection
4. The sealing performance of the oil-immersed transformer is not good and should be aged. The leakage of oil in the operating place is serious, affecting the operation of the equipment and the environment
5. The oil-immersed transformer has a low insulation level and is designed and manufactured according to insulation
