YB series pre-assembled box substation is used in urban high-rise buildings, urban and rural buildings, residential neighborhoods, high-tech development zones, small and medium-sized factories, mines and oilfields, as well as temporary construction of electricity and other places for the power distribution system to accept and distribute power.

　　YB pre-assembled substation has the characteristics of strong set, small volume, compact structure, safe and reliable operation and convenient maintenance, as well as movable, etc. Compared with the conventional civil substation, the box-type substation with the same capacity usually occupies an area of only 1/10~1/5 of the conventional substation, which greatly reduces the design workload and the amount of construction, and reduces the construction costs, and it can be used for the ring network distribution system in the power distribution system, and it can be used for the dual power supply or radioactive terminal distribution system. In power distribution system, it can be used in ring network power distribution system, and also can be used in double power source or radioactive terminal power distribution system, which is a new type of complete set of equipment for the construction and transformation of urban and rural substations at present. YB pre-assembled substation complies with the national standard GB17467-2010 "High-voltage/low-voltage pre-assembled substation".
