Common voltage levels of transformers

Transformers are commonly used power equipment in power systems, mainly used to achieve energy conversion between different voltage levels. According to different usage scenarios and requirements, the voltage level of transformers also varies. The following are common transformer voltage levels:
1. Low voltage transformer: mainly used for household, commercial, and small industrial electricity, with a voltage level usually of 220V/380V.
2. Medium voltage transformer: The voltage level is usually 10kV/20kV/35kV, mainly used in urban distribution networks.
3. High voltage transformer: The voltage level is usually 110kV/220kV/330kV/500kV, mainly used for power grid transmission and substations.
4. Ultra high voltage transformer: The voltage level is usually 750kV/1000kV, used for special occasions and ultra long distance transmission.
