Description
Compared with the 10kV class, the 20kV three phase oil-immersed distribution transformer has some advantages:
- Increase power supply capability
- Ensure the voltage quality
- Debase the electric energy loss in the power system, etc.
It can save the construction fee of the power system. It is the developing product of energy conservation in power systems.
