Product Description

Distribution transformer (High Efficiency) 

It, an energy-saving transformer with low noise and high efficiency, can more than 30 percent of total loss against standard transformers using grain-oriented electrical steel and PHD-core as silicone sheet of oil-immersed transformer. 

 

(1) No-load loss reduction 

Reduced standby power with more than 50 percent decrease of no-load loss against standard transformers by using grain-oriented electrical steel and PHD-core silicone sheet.  
(2) Load loss reduction 

More than 20 percent decrease of load loss by optimal winding design.  

(3) Low noise 

Improved noise to decrease over 7 to 11dB compared with KS standard
