1. Various voltage levels of the power system are converted by power transformers. Amorphous alloy core transformers are used in substations, hub stations, regional stations and terminal stations.
2. Amorphous transformer is a new type of energy-saving transformer with core made of amorphous alloy strip as transformer core. Amorphous alloy core transformer has obvious energy saving and environmental protection, and is a long-term product for the upgrading of distribution network, which should be actively promoted and applied.
