The YB series preassembled substation is an outdoor, publicly accessible substation. The primary side has a rated voltage of 6, 12, 35kV; the secondary side has a rated voltage of 400, 690, 800, 1140 V. The maximum transformer capacity is 6300kVA, with a rated frequency of 50Hz. The product is widely used in power systems, public buildings, high-rise buildings, stadiums, industrial and mining enterprises, transportation stations, and new energy photovoltaic/wind power generation fields. It can serve as a permanent installation or construction site power supply. The YB series can accommodate 6, 12, 35kV switchgear and be placed outdoors, replacing traditional civil substations.
