Outdoor Combined Box-type Substation (European)

Outdoor Combined Box-type Substation (European)

YB series pre-installed substation has the characteristics of strong complete set, small size, compact structure, safe and reliable operation, convenient maintenance, and movable. Compared with conventional civil substations, the floor area of box-type substations with the same capacity is usually 1/10~15 of that of conventional substations, which greatly reduces the design workload and construction volume and construction costs.

Outdoor Combined Box-type Substation Description:

YB series pre-installed substation has the characteristics of strong complete set, small size, compact structure, safe and reliable operation, convenient maintenance, and movable. Compared with conventional civil substations, the floor area of box-type substations with the same capacity is usually 1/10~15 of that of conventional substations, which greatly reduces the design workload and construction volume and construction costs. In the power distribution system, it can be used in the ring network power distribution system, and PJ is also used in the dual power supply or radiation terminal power distribution system. It is a new complete set of equipment for the construction and transformation of urban and rural substations.
