The wind power industry is facing great pressure. It is necessary to improve the design of wind turbines, improve performance and reliability, reduce maintenance costs and save costs per megawatt hour.

Wind turbine operators must ensure that their equipment remains in operation for as long as possible. The performance and reliability of fans are challenged due to their frequent operation in harsh conditions (at sea, in cold or remote areas). At the same time, it also faces problems such as high maintenance cost and long delivery time of replacement parts, which will have an impact on the competitive advantage of power generation.
