Product Features Core High-quality grain-oriented cold-rolled silicon steel sheet are employed, and the whole oblique non-porous banding structure are used here. The core has a multi-level ladder shape, with three joints or five joints, which is of low no-load loss and low noise. Rolled cores are direct rolled by certain special equipments, which gives the advantages including no seam, no corner weight, reluctance reduction, low no-load loss. Amorphous alloy is an advanced core material, which leads to an average reduction of 72% no-load loss and a reduction of 50% no-load current. Coil The...
