good quality wind turbine
Though larger in size and weight ,compared with smaller Hummer turbines ,20000w wind
generator's efficiency is still kept over 0.8 .

And to ensure longer lifespan and better performance ,20000w wind generator adpots S.K.F
bearings .All nuts and blots are made of stainless steel .

Furthermore ,inside the generator we placed a temperature detector .If the temperature rises
over alert level , it will stop working automatically .
