Compared with S11 transformer capacity, three-dimensional volume core no-load loss dropped by more than 25%, decreased by more than 70% no-load current, noise down 7 ~ 10 db (A). With/S13 laminated structure compared with the capacity of transformer, saves the dosage of silicon steel sheet 2 ~ 3% more than 20%, the dosage of copper, no-load current fell by more than 50% drop in 4 ~ 6 db (A) noise.
