how to install vertical arbor wind turbines (wind generators) www.carbonfreeenergy.cn
Silent Wind Turbine . The Vertical Axis Wind-Power Turbine ( VAWT ) is a new product designed . We started the research on VAWT 15 years ago. Now many of the famous experts the world wide have accepted such new technology and this technology will definitely lead the development of the small and middle size wind-power turbines. Following are the detail features of such VAWT: Safe in operation: Due to the usage of the vertical blade and the force support is of triangle form, the wind force will mainly press on the wheel. So the blades will not be able to fall down, to be broken or to be thrown far away. Noise: The way of the turning of the blades is of horizontal and the design of the blade is of the scheme of the wing of the air-plane, so in operation the VAWT will not make any noise. Capacity of wind resistance: Due to the advantage of the design of the VAWT, the press force the turbine suffered is minimized and as the result such VAWT can stand on the extra strong typhoon of 45 m/s. Space requirement: It needs much smaller working space than other kinds of wind-power turbines. Thus not only saves the space, but also aises the working efficiency. Power curve: It needs lower wind speed for its starting and the increasing of the power is slow and stable. So its production capacity is 10-30% higher than other kinds of turbines. Scope of the wind power needed: Due to the adoption of the new control system, this VAWT is suitable to be used in the wind speed scope from 2.0 25 m ...
