transformers Amorphous alloy is a new type of energy-saving material. Its metal atoms are disorderly
amorphous, and its crystal structure is completely different from that of silicon steel, which is more
conducive to magnetization and demagnetization. The iron core sheet is extremely thin, only 0.025mm,
less than 1/10 of that of ordinary silicon steel. This new material is used for transformer cores and features
high saturation magnetic induction, low loss, low excitation current, and good temperature stability.
Amorphous alloy transformers have the advantages of low no-load loss, strong anti-short-circuit capability,
advanced structure, energy saving, and obvious environmental protection advantages, and are currently
ideal distribution transformers for energy saving.
