SZ11-35kV
Future Electric
Product Introduction:
The SZ11-35 series 35kV oil-immersed on-load tap-changing power transformer is a high-efficiency and energy-saving product developed for the global medium-voltage power distribution market. With the application of on-load tap-changing technology, it can change voltage under load without power outage, which makes the problem of fluctuation of grid voltage perfectly solved. Compared with traditional off-load tap-changing transformers, it reduces no-load loss by more than 15% and has excellent energy saving effects. It is fully adapted to the medium-voltage power distribution needs in different regions of the world.
