Amorphous alloy iron core transformer: amorphous material is a new functional material with high permeability, low magnetic saturation, low coercivity, low loss, excellent wear resistance and corrosion resistance, good temperature stability, aging stability and impact vibration resistance. Amorphous alloy resin cast dry-type transformer operates under various harsh environmental conditions, and the magnetic conductivity of amorphous alloy remains unchanged. Compared with silicon steel sheet transformer, the no-load loss is reduced by 70% ~ 80%, and the no-load current is reduced by about 80%. The energy-saving effect is obvious.
