Box transformer substation
The prefabricated substation combines the high voltage electric apparatus, transformer, low voltage electric apparatus to a compact whole set power distribution device, which is suitable for the urban high rise building, resident community, industry park, mine and oil field, field operations and construction field, and it is used to accept and distribute the electrical energy in the distribution system.
This product has the advantages of high performance, compact structure, safe and reliable operation, easy maintenance and it is removable. Compared with normal transformer substation having the same capacity, it only takes 1/10-1/5 of the area taken by the normal transformer substation, which greatly reduces the design workload and the construction workload, the construction work and the construction cost. It is one of the advanced equipment used in the construction and transformation of the transformer substation in the city and town at present.
