    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
