Description
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 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
