Insulation Coated Ei Transformer Laminations

super china factory supply ui core lamination for transformer

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.

Classification of silicon steel sheet

A. Silicon steel sheets can be divided into low silicon and high silicon according to their silicon content. The low silicon wafer contains less than 2.8% silicon, it has a certain mechanical strength, and is mainly used for manufacturing motors, commonly known as motor silicon steel sheets; the high silicon wafer has a silicon content of 2.8% -4.8%. For the manufacture of transformer cores, commonly known as transformer silicon steel sheets. There is no strict boundary between the two in actual use, and high-silicon chips are commonly used to manufacture large motors.

B. According to the production and processing technology, it can be divided into hot rolling and cold rolling, and cold rolling can be divided into grain non-oriented and grain oriented. Cold rolled sheet has uniform thickness, good surface quality, and high magnetic properties. Therefore, with the development of industry, hot rolled sheet tends to be replaced by cold rolled sheet (China has clearly requested to stop using hot rolled silicon steel sheet, which is what was said in the previous period "Replace heat with cold"). Cold rolled silicon steel sheet

Jiangyin hengtong was found in 1989.it is a large scale , standardization, consideration, and information all constitute important factors in the development of steel managing enterprises.
