105 meters! The world's longest onshore wind turbine blade goes offline in Xinyang, Henan province

On June 17, the world's longest onshore wind turbine blade rolled off the line at Mingyang Smart Energy's Xinyang base.

At 9:58 on the same day, in the company's huge workshop, with the windward shell mold slowly opened, a 105 meters long, weighing 30.5 tons of“Big Guy” revealed a mysterious veil.

According to Yin Quan, director of the Blades factory of Henan Mingyang Intelligent Energy Co. , Ltd. , the 105m wind turbine blades being rolled off the line in Xinyang are currently the world's longest onshore wind turbine blades. After installation, the impeller diameter of 216 meters, sweeping area of nearly 37,000 square meters, equivalent to the area of 5 football fields. The blades can further improve the efficiency of power generation at low wind speeds, generating 7,000 degrees of electricity per hour when the units are full. At 300 kilowatt-hours a month for a household, a fan fitted with such blades can produce enough electricity in an hour to power a household for two years.


From 70 meters to 94 meters, to 105 meters now, it's not just simply lengthening the blade. What's changed is not only the length of the blade, but also the innovation of the concept and the breakthrough of technology. Yin Quan said that the production of such an industry-leading onshore wind turbine blade relies on Mingyang's independently developed fiberglass materials, pultruded sheet materials and advanced pultruded technology, at the same time, the relevant technical parameters should be checked repeatedly, so that the blade has an excellent aerodynamic shape, the fan is more safe and efficient operation.

Mingyang Intelligent Energy Co. , Ltd. is the leading wind power enterprise in Henan province. In recent years, through continuous innovation, Mingyang has a 12.4% share of the national smart power market, and the Xinyang base was once the largest onshore wind power equipment manufacturing base in the country with the largest Gross leasable area and stand-alone capacity, its products have been exported to Pakistan, South , Europe, Southeast Asia and other countries and regions.


Since it started production in Xinyang in 2019, the company has made all its own turbines and blades, increasing the power of its wind turbines from 1.5 MW to the current 7MW and its blades from 70m to 105m. The base has an annual production capacity of 1,500 units and an annual output value of over 6 billion yuan, providing strong support for Xinyang's green rise and the green and low-carbon transformation of Henan province.
