this Series product's iron core adopt low-loss high-quality silicon steel sheet, so the transformers have of energy-conserving environmental protection , no need to cut then no cut holes left , so it can dispel the horizontal , vertical seam that the traditional iron core has, decrease loss of magnetism. Utilize orientation of silicon steel sheet fully, dispel the may increased loss of finished product because magnetism way not in accordance with orientation of the silicon steel sheet, it is the substitute of distribution network;
low loss: off-load loss decreased about 30%-45%,off-load current decreased about 80%;
Low noise: decreased 7-10dB
