This ZG-S American type of compact substation is also called combined transformer, or pad mounted transformer, is well applied in power plant substation with low voltage device, high voltage device, transformer and other components integrated, greatly recognized by its functional and energy saving properties.
The sealed tank is made from high quality stainless steel with special design which helps to protect the devices and reduce the heat inside. Excellent cooling and drying system
Temperature control system and humidity control system are installed inside the casing. When the temperature or humidity exceeds rated levels, the systems will automatically work to maintain the safe condition inside the tank. Functional and reliable
It can operate in loop or dual power supply and terminal power supply two ways of power supply. Therefore, it can serve as a substation. Lower cost and higher efficiency
It costs less than the traditional distribution house and only covers the area of about 3cbm.
All the devices are isolated by thick steel board. The efficient insulation system helps to protect the people from electric accident. Easy installation and maintenance.
The installation only requires connecting the cables. The fully sealed transformer design keeps the oil away from the air, so it is free of maintenance.
