Characteristics of wind turbine
1) Direct-drive permanent magnet generator,adopting the strong magnetic material; the overload capacity can reach 2 times than others.
2) Startup wind speed is 3m/s. It’s perfectly and safely to operate with lower wind speed.
3) Safe wind speed is below 50m/s.
4) Rotor blades passed National Wind Runnel Testing and are handmade with mold, the structure are up to par of Aerodynamic standards, has latest airscrew technology, with high efficiency and lower noise.
5) An adapted universal connection between the wind rotor and generator to make wind turbine operate smoothly and without vibration.
6)Closed transmission slip ring, avoid cable enwind together.
7)The principle behind the design of our wind turbine is simple and maintenance-free.
8)There are many kinds of brake systems protect wind turbine safely when the wind speed over rated wind speed.
9)Isobarically direct-current electrification.
10)Thorough corrosion treatment,the wind generators for land use are protected against wind and sand,the wind generators for sea beach use are protected against salt, fog and damp.
