Brief introduction to products

The underground combination transformer is a type of compact combination power distribution device, which integrate transformer, high-voltage load switch, and protective fuse in the oil tank. The underground combination transformer can be installed in the pit and will not take up any space above the ground. It can keep running while immersed in water and is maintenance-free. Based on the above characteristics, it is widely applied in North America. There is a large population in China and the urban population is especially dense, so application of underground combination transformers is of great significance to saving the space occupied by power distribution facility in cities and improving the utilization rate of urban land. Consequently, it is of wide application value in urban network renovation and construction.
