total of x / x pictures

The transformer that is as power supply of rectification device is called rectification transformer. We adopt programmed design using world advanced design technical and manufacturing process, and go through a analysis and quantitative calculation for insulating breakdown mechanism, numerical analysis of electric field, impact characteristic and strength of withstanding sudden short circuit of insulating technology and winding, by combining with many years of manufacturing experience, we make a big breakthrough based on general technology, thus improving the reliability and advancement of our transformers. And our products have many excellent technical performances such as low temperature rise, low loss and sound level with high efficiency and outstanding ability of withstanding short-circuit and overload.
