    Cast resin transformer (High efficiency)
    Using grain-oriented electrical steel and PHD-core as the silicone sheet of cast resin transformer and improving winding method, it optimizes total loss(no-load loss plus load loss) and significantly decreases noise - namely, it is low-noise and high efficient popular breitling avenger replica 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 as the 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
