1. Compositions of amorphous alloy transformers(1)The iron cores of transformers are three-phase three-limb and arranged in two-line matrix. The zerosequenceflux passes through two side yokes and will not flow through the body. Without heat-generating structure,the transformers can meet the requirements of low noise and low loss.(2)Both the high- and low-voltage windings are square copper windings. In case of occasional short circuit,they can bear great mechanical stress and will not lose shape.(3)Equipped with a plate-type heat sink made of cold steel sheet, the body is wholly sealed and maintenancefreefor 20 years.2. Amorphous alloy transformers are characterized by low noise and low loss, whose no-load loss is 1/5 of that ofconventional S9 series. Being wholly sealed, they are maintenance-free and involve low operation cost.3.Amorphous alloy transformers are characterized by low no-load loss and economical operation with comparativelylow load rate, especially suitable for the purpose of electricity consumption of rural and urban residents. Evenin three-shift mines and industrial enterprises with a load rate as high as 50%-80%, choosing amorphous alloytransformers still meet the requirement of years in return of investment. Therefore, the promotion of  amorphousalloy transformers in urban and rural areas can not only reduce the loss of transformers but also bring environmentprotection benefit of constructing few power plants due to its good energy-saving effect, which is of great practicalsignificance in developing an energy-saving society.
