Current Transformers, Nanocrystalline Cores, Shunts, Latching Relays
As new developed materials, nanocrystalline and amorphous cores have the advantage of high permeability and low hysteresis loss. We can provide cores of wide-range dimensions which can serve as important components for different electrical devices and instruments. Due to the
