Low Price High Frequency Power Transformer Electrical Standard EI Silicon Oriented Steel Sheet Iron Core

The requirements for the performance of silicon steel are mainly: ① Low iron loss, which is the most important indicator of the quality of silicon steel sheet. Each country divides the grades according to the iron loss value. The lower the iron loss, the higher the grade. ②The magnetic induction intensity (magnetic induction) is high under a strong magnetic field, which reduces the volume and weight of the iron core of the motor and transformer, and saves silicon steel sheets, copper wires and insulating materials. ③The surface is smooth, flat and uniform in thickness, which can improve the filling factor of the iron core. ④The punching performance is good, which is more important for the manufacture of micro and small motors. ⑤ The adhesion and solderability of the surface insulating film are good, which can prevent corrosion and improve the punching property. ⑥ Basically no magnetic aging.

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.
