Our product advantages

Iron core

Core is made of superior steel, outstanding performance of magnetic conduction. Joint is processed by 45° oblique angled technique, with low loss & low noise.
winding

Winding structure is pie type, which can manage with the field strength effectively. Plus the NOMEX paper used, which ensures very low partial discharge.
fan

Blowers with metal cover, fan’s interface with metal cover
