European type box transformer is a compact complete set of equipment which combines high-voltage electrical equipment, transformer and low-voltage electrical equipment into a complete set of equipment. It is used in urban high-rise buildings, urban and rural buildings, luxury villas, square parks, residential areas, high-tech development zones, small and medium-sized power plants, mines and oil fields, as well as temporary construction sites. It is used to receive and distribute electric energy and provide low-voltage power to users 。
Ybm-12 / 0.4 series European box type transformer substation has the characteristics of strong complete set, small volume, compact structure, safe and reliable operation, convenient maintenance and mobility. Compared with the conventional civil substation, the box type substation with the same capacity usually occupies only 1 / 10 ~ 1 / 5 of the conventional substation, which greatly reduces the design workload and construction amount, and reduces the construction cost. In the distribution system, it can be used in the ring network distribution system, also can be used in the dual power or radiation terminal distribution system. It is a new complete set of equipment for the construction and transformation of urban and rural substation.
