Abstract: With the implementation of new national energy efficiency standards and the promotion of national policies, the transformer manufacturers are required to improve the energy efficiency level of transformers and the grain oriented electrical steel manufacturers are also urged to improve the product level. Baosteel has formed six series⁃more than 70 brands of products, which can meet the needs of different customers. In recent years, Baosteel has developed 0.18 mm new products with excellent magnetic properties. The new products have realized mass production. In this paper, the properties and transformer performance of 0.18 mm products are introduced, expecting favorable for material selection of the transformer manufacturers.

Key words: Baosteel, thin gauge, grain?oriented silicon steel, transformer
