Higher safety and reliability


Direct-drive Technology, Shorter Driven Chain with no High-speed Rotation Components, Higher Reliability
No Lubricating oil system for High-speed Driven Chain, No Slip Ring. Decreasing fire hazard, Higher Safety
Double safety chain design based on patent technology to eliminate speeding accidents and further improve safety
Self-developed electrical system, Mean Time Between Failures(MTBF) is over 2000 hours
The patented technology of magnetic steel box protection prevents magnetic steel from demagnetizing and falling off. No replacement of generator


Excellent Power Generation Performance


155m big rotor diameter, rated power adjustable from 3.0MW to 3.2MW, annual Equivalent Full Load Hours are over 2100h at mean wind speed of 5m/s
More than 60 years' experience on R&D and manufacturing of generating equipment, generator efficiency is 1%~3% higher among domestic market
High efficiency blade design with additional sawtooth, trailing edge and vortex generator, Cp value is higher than 0.49
Self-developed control system perfectly matches the blade to the maximum capture wind energy


Lower Project Capex


Compared to 2.0/2.5MW turbine, the number of units can be reduced by 17~34%, the capex for land acquisition, road construction, equipment instalation, transmission line, etc. can be reduced significantly


Lower O&M Cost


Direct drive technology,without regular replacement of gearbox oil,filter element,and carbon brush of generator,less maintenance duration
Fewer components,lower failure,shorter downtime due to regular maintenance,less AEP loss
Less consumable material to lower O&M cost
