The amorphous alloy transformer is a low-loss and high-energy-efficiency power transformer. The transformer uses iron-based amorphous metal as an iron core, and because the material has no long-range ordered structure, the material is easier to magnetize and demagnetize than common magnetic materials. Therefore, the iron loss (i.e., no-load loss) of the amorphous alloy transformer is 70-80% lower than that of the conventional transformer using silicon steel as the iron core. Because the loss is reduced, the power generation requirement is also reduced, and the emission of greenhouse gases such as carbon dioxide is also reduced correspondingly. Amorphous alloy transformers are used in large-scale developing countries such as china and india in a large scale, based on energy supply and environmental protection factors.
