Mini European type compact substation

Main Function And Features 

Small volume, compact structure reliable power supply and easy for installation; it can realize single power supply, double power supply, or ring net supply with double-fuse protection, low running cost.The casing surface is treated by electrostatic painting and has good wearing resistance. It is applicable to both ring network and single/double power supply, is convenient  for shifting and can enhance the reliability of power supply. The transformer  adopts environment-friendly S11 series spiral core, non-excited voltage regulation, full-enclosed type, featuring energy saving and low noise. The amorphous alloy transformer is also available if required by clients. HV load switches and protective fuse are placed in oil filled iron tank, and the tank is full-enclosed structure. The LV room is provided with watt-hour meters, voltmeters and breakers of four outgoing lines, reactive power compensation can also be provided if necessary. It uses S11 series spiral core transformer, its idle loss is 30%~40% lower than S9, and noise 7~10dB lower than S9.

Compared with traditional substations, the Mini substation offers several unique advantages. Conventional substations are generally large, heavy, and require significant land area, which often makes them unsuitable for crowded urban environments or sites with strict space limitations. Their installation and transport usually involve specialized trucks, cranes, and complex logistics, increasing both cost and handling risk.

In contrast, the Mini substation is designed with a compact footprint and reduced overall volume, allowing it to be installed in areas where standard substations would simply not fit. Despite its smaller size, it still delivers all essential functions—including transformation, protection, switching, and control—ensuring no compromise in performance. Its lightweight and modular structure makes it much easier to transport and install, often without the need for oversized vehicles or heavy lifting equipment.

Ultimately,the Mini substation provides a flexible,efficient,and safer alternative,especially for urban projects,temporary installations, and distributed energy systems, where space and convenience are critical.
