Description
The unitized substation combines high-voltage electrical appliances, transformers, and low-voltage electrical appliances into a compact complete power distribution device, which is suitable for urban high-rise buildings, residential communities, industrial parks, mines and oil fields, as well as operations and construction. It is used to receive and distribute electrical energy in the power distribution system. The product has the advantages of high performance, compact structure, safe and reliable operation, easy maintenance and mobility.
Compared with ordinary substations of the same capacity, it only occupies 1/10-1/5 of the space, which greatly reduces the workload and cost of design and construction. It is one of the selective complete sets of equipment used for urban and rural construction and reconstruction.
