Anti Corrosion ASTM EI Lamination Core

Standard UI Electrical Silicon EI Lamination Core Sheet Reactor

Hot Sale Standard UI Electrical Silicon Laminated Steel Sheet Reactor with high frequency

In order to increase the magnetic induction intensity, an iron core is used in the transformer. When an alternating current is passed through the coil of the transformer, a large eddy current will be generated in the iron core, which not only consumes a lot of energy, but also may burn these. device.
In order to reduce the eddy current and its loss, the laminated silicon steel sheet is usually used instead of the entire iron core, and the plane of the silicon steel sheet is parallel to the magnetic induction line. On the one hand, due to the large resistivity of the silicon steel sheet itself, on the other hand, the insulating varnish or a natural insulating oxide layer is applied between the sheets, which limits the eddy current to the content of each sheet, greatly reducing the eddy current, thereby reducing the Loss of electrical energy.

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.
