Product characteristic:
The transformer which can supply power for rail traction system is called rail traction transformer. We adopt advanced design technology and manufacturing process in the world, as well as programmable design, via 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, and combine with many years of manufacturing experience, making our product have a big breakthrough based on conventional 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.
