YB series prefabricated substations (hereinafter referred to as box type substations) are suitable for electric power users such as subways, airports, ports, stations, industrial and mining enterprises, and various public buildings (such as hotels, hospitals, high-rise buildings, stadiums). Used for AC 50Hz and 60Hz, high voltage side rated voltage 3.6~40.5kV, low voltage side rated voltage 220~690V, rated capacity 2000kVA and below system. It can be used as a permanent power supply device and as a temporary power supply for construction sites. It is a pre-installed substation with outdoor use conditions accessible to the public, which can replace civil substations.
