The iron core of amorphous alloy core distribution transformer is manufactured by amorphous alloy with soft magnetic characteristic, which can further reduce the distribution loss and ease the air pollution. Compared with the conventional silicon steel, the new fashioned transformer can reduce 75% of the no-load loss and produce high energy-saving effects. Amorphous alloy iron core featured as low loss (1/3-1/5 of silicon ), low coercive force, low exciting current, high resistivity, good temperature stability, etc. The transformer manufactured by amorphous alloy core has 70-80% reduction of no-load loss than silicon S9 product, and 20% reduction of no-load current than S9 series. Amorphous alloy is a new type of energy-saving material, rapid solidification manufacturing technique is adopted while using iron, boron and other elements as materials. Its physical state performed as disorder non-crystal arrangement of metallic atoms, which is totally different from the crystal structure of silicon, while can be easily magnetized and demagnetized. The new material is used in the iron core of transformer, which make it relative easy for magnetization and demagnetiz
