Switching Station
The DFW-12 Medium Voltage Switching Station is designed for the reception and distribution of 10KV power, equipped with medium voltage input and output lines for power redistribution. It functions as an extension of the substation busbar, addressing limitations in substation line intervals or corridors, and provides power support in the area. Typically configured with two inputs and multiple outputs, it can be equipped with circuit breakers or load switches as required. Its primary functions include reducing the scope of accidents and power outages, increasing feeder lines, and improving power supply reliability. It is widely used in urban power grid construction.
