2MW wind turbine gearbox

Product Introduction

      We are the earliest enterprise developing and manufacturing independently MW class wind power gearboxes in China, As a leader in the wind power transmission field, we have the experience in wind power gearbox and yaw & pitch drives R & D, manufacturing, have provided over 12,000 sets of various wind power products for ten plus countries and regions cumulativelyover ten years development,through constant innovation and optimization, we have developed and manufactured the 750KW-6MW series wind turbine gearboxes and yaw & pitch drives with independent intellectual properties.Under the authorization of the Ministry of Science & Technology of the State in 2011, the “national engineering and technical center for wind power transmission and control components” was established.

We are the first domestic wind power gearbox manufacturing enterprise obtained GL certification. Our products have passed successively 20 plus design, production and safety certifications such as GL, DNV, Dewi-OCC, TUV, CE, etc.

Product advantage
 In design, the operating conditions of the wind units are considered sufficiently to calculate and analyze the parts and components carefully. The products are characterized by being light in weight, compact in structure, high torque carrying capacity, being reliable in performance, etc. and suitable for wind sites with different grid frequencies, wind scales, natural environments. 
Our Company
