(Summary description)The voltage level of the prefabricated substation is 6~35kV for high voltage and 220/380V for low voltage.
Three-phase AC, 50Hz, rated capacity is generally 30 ~ 1600kVA.
Transformers in prefabricated substations are divided into two types: dry type and oil immersed.

The voltage level of the prefabricated substation is 6~35kV for high voltage and 220/380V for low voltage.
Three-phase AC, 50Hz, rated capacity is generally 30 ~ 1600kVA.
Transformers in prefabricated substations are divided into two types: dry type and oil immersed.
Prefabricated substations generally consist of four parts: high-voltage switchgear, low-voltage distribution panel, distribution transformer, and enclosure.
Scope of application:
Prefabricated substations can be used as ring network type and terminal type power transformation and distribution devices. Widely used in residential quarters, industrial and mining enterprises, hotels, hospitals, shopping malls, airports, parks, railways and other outdoor places.
Conditions of Use:
1) The altitude does not exceed 1000m;
2) Ambient temperature: the highest temperature is 40°C, the lowest temperature is -25°C, and the highest daily average temperature does not exceed 35°C;
3) Relative humidity: the daily average value does not exceed 90% (+25°C);
4) The outdoor wind speed does not exceed 35m/s;
5) The slope of the ground is not greater than 3°;
6) The sunlight radiation shall not exceed 1000W/m;
7) There is no danger of explosion, fire, chemical corrosion and severe vibration at the installation site; when it is different from the above normal use conditions, it should be resolved through consultation between the user and the manufacturer.
8) The seismic intensity is 8 degrees.
