The Trend of Large-Scale Wind Turbines

        In recent years, the trend of large-scale wind turbines has continued to accelerate, and complete machine manufacturers have launched ultra large megawatt units. As mainstream models, 5MW to 7MW units have also been widely used. With the expansion of the unit capacity, the size and weight of the host, as well as the length and weight of the blades, also increase. In the actual lifting process, the difficulty of lifting also increases accordingly. How to complete the lifting of large units with high quality and efficiency has become a hot topic in the industry.

        Sany Heavy Energy participated in the construction of the 200000 kilowatt/80000 kilowatt hour energy storage supporting Jimunai wind power project in Altay. 32 Sany Heavy Energy 6.25MW wind turbines were installed, which is a typical large-scale unit application case. Based on past experience, lifting a large megawatt unit takes about 2 days, while the project only takes 44 days to complete the lifting. The fastest lifting time for a single unit is 21 hours, and it has been successfully connected to the grid recently.
