Grain-oriented electrical steel is an electrical steel with a silicon content of approximately 3%. It has outstanding magnetic properties in one direction or rolling direction. The reason they have excellent magnetic properties in one direction is due to their crystal structure, in which the grains are well aligned.
Grain-oriented electrical steel is commonly used in the production of inductors, generators, HVDC or high-voltage direct current transmission systems, magnetic shielding, reactors and other cores that require low core losses and high magnetic permeability at high flux densities. It can also be used in different types of transformers such as high-efficiency stacked core transformers, distribution transformers, power transformers, etc.
