The clean, low-carbon, safe and efficient modern energy system has received attention, and the wind energy industry has developed faster. The development of new energy technology cannot be achieved without the support of imported equipment and spare parts, such as elevation and angle encoders, fans, motors, inverter controllers, power generation systems, and generator sets All of them have been perfectly applied in the wind energy industry.
