To meet most of customers' requirements, we promote an economy wind turbine generator which is cheap and good quality. Considering the generator can start easily, our engineers develop the lower start-up wind speed. Start the wind turbine generator only needs 2m/s wind speed. 20-year long life-span wind power generator is deserved you to own it. What kind of region can be installed wind turbine? Small wind turbines should be applied in the regions which wind resources is sufficient. The annual average wind speed should be more than 3m/s, the effective wind speed 3-20m/s should be more than 3000h in accumulation per year. The density of 3-20m/s effectively average wind power should be more than 100W/m 2.It should be noted that choosing the rated design speed wind turbine is in conformity with local design speed. It is significantly in making use of wind resources and in economic aspect. Wind tunnel test proves that the fan power transformation of the impeller in the direct ratio with wind speed, that is to say, the wind speed decide the output electrical power.
