Transformer cores are generally made of silicon steel sheets. Silicon steel is a type of steel containing silicon (also known as silica). The reason for using silicon steel to make transformer cores is that it is a highly permeable magnetic material, which can generate a strong magnetic induction intensity within an energized coil. This allows the volume of the transformer to be reduced. Read More

The lamination process for transformer cores constitutes the core stage of core manufacturing; by stacking silicon steel sheets in a specific configuration, it establishes a closed magnetic circuit while minimizing magnetic losses. This process entails several steps—including material pretreatment, Read More
