Our HYE wind turbine belongs to Class III in accordance with wind turbine international grade, please refer to following chart, 

 

In order to be compatible with extreme load of international safety standard, while calculation of the load, the 

and all of wind speed which is calculated by 

  should be reduced by 

7%. 
As we all know, the huge wind, storm or hurricane usually does not last for a long time, assuming a huge wind occurred once in 50 years, the average maximum wind speed within 5 
seconds at hub height is represented by 

, it is calculated by 

multiply coefficient 1.4, that is 

=1.4  

 

From above explanation, the survival wind speed of Class III wind turbine is: 
 

=1.4 -1.4 *7%=1.4*37.5-1.4*37.5*7%=52.5-3.68=48.82m/s (

＜50m/s) 

 
 

So this is why the survival wind speed of HYE wind turbine is 50m/s.   
Generally speaking, the safety and operation of wind turbine is closely related with matching components, correct pole installation, correct system cable connection, these three factors we
