Abstract: As the fourth intelligent plant of silicon steel put into production, Baosteel has formed six series,more than 50 brands of grain-oriented electrical steel products, such as P series of high magnetic induction grain-oriented electrical steel, R series of laser scribing grain-oriented electrical steel, G series of ordinary grain-oriented electrical steel,LM series of low noise grain-oriented electrical steel,W/Y/Z series of special coating grain-oriented electrical steel, and HS series of heat resistant grain-oriented electrical steel, which can meet the needs of different customers. In this paper, the application of Baosteel's thin gauge grain oriented electrical steel products, especially B23R075, B20R070 and B18R060 were introduced for power transformer.

Key words: Baosteel, grain-oriented electrical steel, B23R075, B20R070, B18R060, power transformer
