Small wind turbine EWTH 20KW

Small wind turbine EWTH 20KW

Features:

  • Excellent power output performance during the common wind speed between 5m/s and 9m/s
  • High efficient synchronized PMG generator with low starting torque
  • Lower RPM rotational speed avoid the risk of over speed malfuction and bring lower noise emission
  • Multi‐protection systems ensure high reliability and safety during high wind (passive self‐furling +
    electromagnetic brake + manual brake)
  • Equipped with high quality NSK brand sealed bearing
  • Long lifespan design by using superior aluminum alloy and cast steel in accurate die‐casting tech and
    the anti‐corrosion treatment for all  kinds of circumstances
