The prefabricated compact substation transformer is one kind of compact complete set of distribution equipment which designed combining medium voltage switchgear, low voltage switchgear, distribution transformer, energy metering devices and reactive power compensation devices into one or several boxes according to a certain wiring scheme. It is suitable for three-phase AC systems with a rated voltage of 11KV or 33KV for line and distribution of electrical energy.
With the advantage of compact size, prefabricated compact substation transformer was widely used in the three phases of the power distribution system with the voltage rating from 11kV to 33kV for electricity distributing. The protection degree reached IP55, so it could be installed outdoor by occupying the small area.

Prefabricated Substation Transformer Feature
- The enclosure material can be aluminum alloy plate, stainless steel plate, composite plate, glass fiber reinforced cement plate, etc.
- The base of the substation is made of galvanized channel steel or cement, with strong corrosion resistance and sufficient mechanical strength.
- The roof applies double layer structure, which has good heat insulation, radiation protection and ventilation effect.
- Each compartment of the substation is separated by iron plates to form an independent small chamber. Each compartment is equipped with lighting facilities. The top of the transformer compartment is equipped with an automatic exhaust device to adjust the temperature of the transformer compartment.
- The color of the substation can be customized to fit with the surrounding environment.
- The transformer can be configured with oil immersed transformer or dry type transformer accordingly.
