Not necessarily, the size of the silicon content of silicon steel sheet on the quality of the transformer is not very big influence, and orientation and no orientation is related to the type of the iron core. Secondly, even if the same type of iron core if you process is not good, the quality difference is very big, the difference sometimes even as high as forty to fifty percent.
The heat treatment and wire winding process of a good core and the same material is very critical. A good heat treatment only needs a very small 10mA excitation current to reach 15,000gauss, while a bad heat treatment may need 50mA excitation current to reach the corresponding 15,000gauss. The difference between the two is very big. From a professional point of view to judge the good and bad iron core, mainly through the excitation current, iron loss, saturation parameters several indicators to carry out comprehensive price.
