Our product advantages

  • Iron core

    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.


  • fan

    fan

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


  • winding

    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.


  • coil

    coil

    Coil is made of oxygen-free copper, low resistance and low loss, but high efficiency. 


  • insulation material

    insulation material

    Insulation material: NOMEX paper of DUPONT brand, insulation Class C, heat-resistant is up to 220℃, with excellent overload capacity.
