Amorphous metal transformer basic introduction:

In order to meet the high requirements of power users for energy saving and consumption reduction, GE Transformer has newly launched a kind of amorphous alloy hermetic transformer with low loss. The amorphous metal transformer is a new type of transformer made of amorphous alloy magnetic material iron core. This product is oil-filled and sealed, and its principle is the same as that of the sealed power transformer. The essential elements of amorphous alloys are iron, nickel, cobalt, silicon, boron, carbon, etc. It is an isotropic soft magnetic material with low magnetization power and no structural defects that hinder the movement of domain walls. The thickness is extremely thin, only 0.027mm, and the filling factor is correspondingly tiny, only 0.75~0.8. The resistivity is very high. It is a silicon steel 3~6 times that of silicon steel sheets, and 5 times the hardness of silicon steel sheets. Amorphous alloy materials are susceptible to stress.
For SH15-M-30~2500kva/6~10kv series products, the no-load loss is 70% lower than the GB/T6541 standard value. Implementation of the standard GB/T25446 “Technical Parameters of Oil-immersed Amorphous Alloy Core Distribution Transformer”, SH15 Amorphous metal Oil-immersed Transformer can be used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises, and power plants, especially suitable for places with high requirements for flammable, explosive and fire protection. Therefore, the amorphous alloy transformer is the most ideal energy-saving power distribution equipment in the indoor power supply network
