The blade is 143 meters long and has an impeller diameter of 292 meters. It is one of the wind turbine blades with the largest impeller diameter in the world. 

The carbon fiber fabric used in this blade is exclusively supplied by China’s Hengshen, “which highlights the company’s competitiveness and influence in the field of carbon fiber wind power”, according to the company.

Hengshen has five thousand-ton carbon fiber production lines with an annual production capacity of 5,000 tons of carbon fiber. The product portfolio covers raw silk, carbon fiber, sizing agents, fabrics, liquid resins, adhesives, prepregs, carbon fiber composite parts, and aviation composite structural parts. 

In 2021, Hengshen’s 24K carbon fiber, fabric and carbon plate products obtained DNV certification from the international authoritative certification agency, becoming the first domestic carbon fiber unit to obtain this certification. Up to now, Hengshen has supplied products such as carbon fiber pultruded sheets and warp-knitted fabrics in batches to domestic and foreign wind turbine manufacturers such as Envision Energy, Shanghai Electric, and Mingyang Smart Energy.
