Full-size Wind Turbine Blade Testing

The Jiangsu Branch is located in the Economic and Technological Development Zone of Lianyungang City, Jiangsu Province, adjacent to the port and expressway, offering excellent transportation and industrial synergy conditions. The company operates two 25 MW full-scale wind turbine blade structural testing platforms, equipped with an advanced five-degree-of-freedom (3+2) testing system, boasting leading domestic technical capabilities. It has the capacity for structural testing ranging from small components to full-scale blades up to 180 meters in length. The maximum test power of the platform exceeds 25 MW, supporting a blade root bolt circle diameter of 7.8 meters. Static tests achieve 20-point synchronous loading, while fatigue tests feature multi-mode excitation and closed-loop control, meeting the requirements for high-load, high-precision testing. Additionally, the company has established a specialized oil analysis laboratory, providing wind turbine equipment lubrication condition monitoring and fault diagnosis services, fully supporting wind power operation and maintenance testing. The company has now developed a full-chain testing and technical support capability covering raw materials, components, full-scale testing certification, and wind farm operation and maintenance services.
