Introduction
Oil immersed transformer is one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings.
Oil immersed type transformer main types:
1. Non enclosed oil immersed transformer: it mainly includes series products such as S8, S9, S10, etc., which are widely used in industrial and mining enterprises, agriculture and civil buildings.
2. Closed type oil immersed transformer: it mainly includes S9, S9-M, s10-m and other series of products, which are mostly used in places with many oil and chemical substances in petroleum and chemical industries.

3. Sealed oil immersed transformer: mainly bs9, S9 -, S10 -, s11-mr, SH, sh12-m and other series products, which can be used for power distribution in industrial and mining enterprises, agriculture, civil buildings and other places.
4. There are also various special transformers for special purposes.
For example, the high-voltage transformer for test, the transformer for electric furnace, the transformer for welding and the transformer for SCR line are used for the voltage transformer and current transformer of measuring instrument.
