C45 steel as spindle has a strong resistance to corrosion. 3, the blade wavelike blade is according to the precise principles of fluid mechanics and design, to increase the exposure and the angle of the blades with the wind, the greater the rotational force can be obtained in the breeze, to avoid the respective direction of the wind was poured into air duct phenomenon, and the utilization of each direction of the wind to accelerate the rotational speed of the turbine head, which fully played rain, snow, and the exhaust. As a result of the wave shape, mechanical strength greatly enhanced ability to pressure similar products! %% @ #% # @%% 12% @ # # @%% @ # # @% zero cost to run 24 hours without personnel to operate, light weight, green, no noise and long life, easy to install and quick applicability widely, unique round appearance (Taiji principle to resolve a horizontal push force) and the support structure to ensure that the turbine can withstand typhoons.
