Magnetic Properties
The magnetic properties of the product is featured by its low core loss, high permeability and excellent application performance
Thickness Tolerance
The good thickness tolerance is characterized by small difference in thickness in a direction parallel to the direction of rolling, small difference in thickness in a direction perpendicular to the direction of rolling, and high lamination factor.
Processing Properties
The product is suitable for punching and cutting with excellent dimensional tolerance.
Insulation Coating
The insulation coating has small color deviation, good adhesiveness and excellent resistance to heating and corrosion with high insulation coating resistance. There are several types of insulation coating available for production. According to the test results performed by the professional inspection organizations, the contents of hazardous substances comply with all the prevailing international and domestic environment protection laws and regulations including EU RoHS and REACH regulations.
E-type silicon steel sheet is also known as shell-type or Japanese-type silicon steel sheet. Its main advantage is that the primary and secondary coils share a wire frame and have a higher window space factor (space factor Km: net cross-sectional area and window of copper wire Area ratio); the silicon steel sheet forms a protective shell for the winding, making the winding less susceptible to mechanical damage; at the same time, the silicon steel sheet has a larger heat dissipation area and less magnetic field dispersion from the transformer. However, its primary and secondary leakage inductance is larger and the external magnetic field interference is also greater. In addition, because the average circumference of the winding is longer, under the same number of turns and core cross-sectional area, the EI-type core transformer uses more copper wire.
