Chinese OEM unveils the world’s longest onshore wind turbine blades
At 430 feet (131 meters), the SY1310A is the latest engineering feat from Sany Renewable Energy that sets the record for the world’s longest wind turbine blades on land. The company intends to deploy the blades on its 15 MW turbines, which are set to be the most powerful onshore wind turbines around.
Chinese energy giant Sany Renewable Energy has embarked on a project to build the most powerful wind turbines ever deployed on a terrestrial wind farm.
Stationed at a mammoth facility in Bayannur, Inner Mongolia, the blades are ready for testing and deployment. The SY1310A blades are much thicker and longer than previous generations and have already clinched the title of the longest onshore wind turbine blades. At 430 feet (131 meters), it even surpasses the blades of most offshore turbines, including the current CRVT prototypes.
The Chinese turbine manufacturer has automated most of its manufacturing operations to cut down on construction time and improve efficiency. With a prefabrication failure rate of almost zero percent, each blade takes less than 30 hours to manufacture—ten hours less than the industry average.
In its press release, Sany Renewable also highlighted its implementation of IoT technologies, including the use of a ‘digital twin’ virtual factory for remote supervision of all procedures carried out in the physical factory.
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.
After the required component and full-size testing, the Chinese engineering firm intends to install these mammoth blades on its planned 15 MW onshore wind turbine. A global rollout is, however, highly improbable.
