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.
