What is a prefabricated substation?
A prefabricated substation, also called a box-type or compact substation, combines medium-voltage switchgear, a distribution transformer and low-voltage switchgear in one factory-built enclosure. It is delivered ready to connect, which shortens site work. Chinese makers offer European-style units with separate compartments and American-style pad-mounted units with the transformer and switching in one tank.
What buyers compare
- European-style (compartments) or American-style (combined)
- Transformer rating and type
- MV switchgear type, often a ring main unit
- Enclosure material, IP rating and ventilation
- Standard: IEC 62271-202
