How are the waste power transformers respectively oriented silicon steel sheets?
Mainly look at the type of transformer, such as: S7, S9, S11 and so on, are all oriented transformers.
After the 80s of last century, the domestic transformer, that is, after the S7 type transformers are cold-rolled, oriented silicon steel sheet. It's hard to say before 80s.
Mainly looking at what age products?. S7, I can assure you that the cold-rolled silicon steel sheet is oriented. The iron core loss will be greater if compared with the current silicon steel sheet.
