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 sheet iron core is an iron-silicon alloy formed by adding a small amount of silicon (generally below 4.5%) to pure iron, which is called silicon steel. These iron cores have the highest saturation magnetic induction intensity value of 20000Gs; because of their good magnetoelectric properties, easy mass production, cheap price, little mechanical stress and other advantages, they are extremely widely used in the power electronics industry. Such as power transformers, distribution transformers, current transformers and other iron cores. [1]
It is also the material with the largest amount of magnetic materials for power transformers. Especially suitable for low frequency and high power. Commonly used are cold-rolled silicon steel sheet DG3, cold-rolled non-oriented electrical steel strip DW, cold-rolled oriented electrical steel strip DQ, suitable for all kinds of electronic systems, household appliances, medium and small power low frequency transformers and chokes, reactor , Inductor iron core, this kind of alloy has good toughness, and can be processed by punching and cutting. The iron core has lamination type and winding type. However, the loss increases rapidly at high frequencies, and the general use frequency does not exceed 400 Hz.
