Toroidal Mini Core

The cores are wound by automatic core winding machine with a continuous silicon steel strip and are annealed in high vacuum furnace under protection atmosphere or in continuous tunnel furnace. The impregnation is done in vacuum impregnating equipment. The advanced manufacturing process makes full use of grain orientation of silicon steels, so that the core enjoys advantages such as compact volume, lightweight, low magnetic leakage and humming, high efficiency and stable quality. Applications: Power transformers, current transducers, instrument transformers, inductors, ballasts, AF transformers, magnetic amplifiers, voltage stabilizers and regulators
