Improved construction, compact size, superior reliability

C-class Dupont Nomex paper 

Highly insulating

With electromagnetic and structural optimization design, small size and lower noise

The structure of coil is non-encapsulated with excellent property of flame retardant

Largely reduce harmonic impact by adopting silicon-steel sheet/ low current density design

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.
