Standard EI AISI 0.23mm Silicon Electrical Steel

Excellent Design Standard EI Silicon Steel Sheet Iron of transformer core

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.

Silicon steel for UHV AC transformers has always been the technical field of foreign companies. In international trade, long supply cycles and high prices often occur. Compared with the status of foreign UHV transformer silicon steel products as "unusual goods", domestic high-performance oriented silicon steel urgently needs breakthroughs in technical difficulties such as magnetic properties, quality stability and yield rate, and the design of silicon steel sheets for UHV transformers is needed Selection criteria and innovation of application performance detection and evaluation methods under complex working conditions.
