R & D

Scientific Research Cooperation

Undertake national and provincial research projects

Established a joint laboratory for silicon steel materials and applications with the National Research Centre for Silicon Steel Engineering Technology

Cooperative research and development of materials with DuPont (insulating paper), ELANTAS Germany (insulating varnish) and Ruihuatai (insulating film for aerospace).

We have signed cooperation agreements with more than 100 peer manufacturers to share the three-dimensional core winding technology and drive the technological upgrading of the transformer industry.
