Product Description


Product Description
 
Specifications:
 
Transformer Substation 
1.High quality High voltage room. 
2.Excellent forced-air cooling system. 
3.Strong tank protection.
 
compact Substation/ Transformer Substation  Product Description:
 
Compact substation/Transformer Substation, also called pad-mounted transformer, is a functional and energy saving combined transformer which integrates the high voltage device, low voltage device, transformer and other components.
 
1.Strong tank protection 
The sealed tank is made from high quality stainless steel with special design which helps to protect the devices and reduce the heat inside.
 
2.Excellent cooling and drying system
Temperature control system and humidity control system are installed. When the temperature or humidity reaches certain levels, the systems automatically work to maintain the safe condition inside the tank.
 
3.Transformer Substation Functional characteristics 
Functional and reliable 
It owns loop or dual power supply and terminal power supply two ways of power supply. Therefore, it can serve as a substation. 
 
4.Lower cost and higher efficiency
It costs less than the traditional distribution house and only covers the area of about 3cbm. 
 
5.Safe 
All the devices are isolated by thick steel board. The efficient insulation system helps to protect the people from electric accident.
