The power transformer is increasingly widely applied by existing manufacturers and equipment technology and environmental protection department, while in order to produce the power transformer with a steady quality and increase the accuracy and precision of power transformer, the materials required and the necessary time to be consumed are quite huge.

The insulating materials of high quality and the iron core materials of high efficiency are absolutely necessary for the excellent power transformer, which makes it possible to well transform the rating of power supply and realize a relatively steady transformation of different alternating current at the same time. Besides, some impregnated materials are also of significance, and the painting components of good strength will be chosen as the electronic materials in general, which may enhance the insulation effect further. Therefore, the power transformer is getting more and safer and steady nowadays, and has achieved the higher efficiency.
