Chinese OEM unveils the world's longest onshore wind turbine blades

Durability is the chief concern for wind turbines, and it becomes increasingly difficult with the size and scale of the blades. Courtesy of a thicker airfoil, a reinforced carbon fiber main beam and a metal mesh for lightning protection, Sany's SY310A blades are built to last. And although they aren't 100% recyclable, the trailing edge insert is made of recycled polyurethane structural parts that can be easily circulated after the lifespan of the turbine.
