Material introduction:
wind turbine blades:
We utilize high strength glass fibre reinforced plastic and epoxy resin to make blades.The wind rotor operate well(stably and quietly).This kind of new aerofoil is elaborately designed by aerodynamic and hydromechanical specialists(experts).It start-up wind speed(or cut-in wind speed)is very low,and the wind energy (rotor power)coefficient is very high.

Generator:
It is made up of the superior high strength permanent magnetic material. The volume is small and the weight is light, the generating electricity coefficient is high.The generator specialist(expert) use special electromagnetic technology to make the generator have extremely low start-up drag torque, which can make sure the VAWT start-up in the gentle breeze.The generating electricity coefficient, start-up performance and overspeed overload capacity of generator are all in leading position in this field.

1.The warranties for our wind turbines is 2 years.
2.Our product passed CE,ISO certification,the generator assembly is high reliability,high efficiency,light weight,good surface and sealing.
3.Besides,our BF-H series wind power generating set utilize a new aerofoil vertical axis wind wheel and magnetic suspention structure,the wind energy cofficient is very high,the start-up wind speed is very low,the anti-wind capability is high.have no noise.
4.What's more,the wind turbine's tower our engineer designed is free standing tower for security, as the generator and blades are much more big and heavy,so the price is a little bit high.
5.Generally speaking,our wind turbine is very fair in configuration,superior in quality,high in security.and the warranties for our wind turbines is 2 years. you can use it enduringly and safely.
