Our product advantage:
 
1.Wind turbine blades: We utilize high strength glass fibre reinforced plastic and epoxy resin to make blades. Low Noise. No need to adjust and good quality of balance. No shaking. High strength, fatigue resistance. 
This kind of new aerofoil is elaborately designed by aerodynamic and hydromechanical engineers.Its start-up wind speed or cut-in wind speed is very low, and the wind energy coefficient is very high.
  
2.Generator:It is made up of the superior high strength permanent magnetic material. We use high grade NdFeB permanent magnet for generator. The magnetic sheet is Neodymium iron boron not ferrite. Neodymium iron with long life time than ferrite and not easy be demagnetized. The stator is made of 470 silicon steel sheet not iron sheet. The generating electricity coefficient is high.
  
3.The low starting torqure is designed by our mechanical engineer but also assure the high generating efficiency by improving the inner structure.With scientific design and practiced experience,the machine has stable and high efficiency.

4.  The wire package in the generator is made of copper wire which can resist 160 centigrade heat. High insulated performance, high magnetic permeability, High generating efficiency.
