Box Substation
YB□-12 Prefabricated Substation
Compact 12kV prefabricated substation integrating HV, transformer and LV compartments.
YB□-12 is a factory-assembled prefabricated substation (also known as box-type or pad-mounted substation) combining HV switchgear, a transformer and LV switchgear in a weather-proof enclosure. It shortens on-site civil works and commissioning time.
