High magnetic induction oriented silicon steel sheet is the main material that constitutes the transformer core.
The basic requirements for the transformer core material are low ferromagnetic loss at a certain frequency and magnetic flux density and high magnetic flux density at a certain magnetic field intensity. The size of the no-load loss of the transformer is mainly determined by the material of the silicon steel sheet. In addition, it is related to the design and manufacturing process of the iron core.

The silicon steel sheets have high surface flatness and uniform thickness, which allows them to fit closely and reduce air gaps when stacked to form an iron core.
The existence of the air gap will increase the magnetic resistance and reduce the efficiency of the transformer, while good stacking performance can ensure the uniformity of the magnetic permeability of the core, further improving the performance stability of the transformer.
For example, in the production process of dry-type transformers, the precise stacking of silicon steel sheets can ensure the stability and accuracy of the transformer's output voltage and meet the needs of various precision electrical equipment.
