Main classification of distribution transformers

Distribution transformers are divided into oil immersed transformers and dry-type transformers according to the different insulation media; According to different voltage regulation methods, it can be divided into non excited voltage regulation transformers and on load voltage regulation transformers.
Oil immersed transformers are divided into:
1) Non enclosed oil immersed transformers: mainly including S8, S9, S10 and other series products, widely used in industrial and mining enterprises, agriculture and civil buildings.
2) Enclosed oil immersed transformers: mainly including S9, S9-M, S10-M and other series products, commonly used in places with high oil pollution and chemical substances in the petroleum and chemical industries.
3) Sealed oil immersed transformers: mainly including BS9, S9-, S10-, S11-MR, SH, SH12-M and other series products, can be used for power distribution in various places such as industrial and mining enterprises, agriculture, civil buildings, etc.
Dry type transformers are divided into:
1) Sealed coil dry-type transformers: mainly including SCB8, SC (B) 9, SC (B) 10, SCR-10 and other series products, suitable for high-rise buildings, commercial centers, airports, stations, subways, hospitals, factories and other places.
2) Non encapsulated coil dry-type transformers: mainly including SG10 series products, suitable for high-rise buildings, commercial centers, airports, stations, subways, petrochemicals and other places.
