The giant Chinese SL5000 wind turbine is the largest in the world. It is independently developed and manufactured by China. There are only two units in the world. It is the largest wind turbine in history. It was independently developed by a Chinese company. It not only has complete intellectual property rights, but also leads the world in technology.
The SL5000 has a huge body. It can take off and land helicopters on the cabin. The diameter of the blade alone reaches 128 meters, and the height of the wind wheel is more than 40 stories. The nominal lifespan is approximately 20 years. In order to ensure that no problems will arise in practice, various rigorous and precise tests have been carried out. Testing the blades alone took 4 months to enable them to withstand the strongest natural forces. And after vibrating 5 million times, it's still intact after simulating a lifespan of 20 years. Wind turbine bearings are the most vulnerable parts, which is why the bearings of the SL5000 must defy the highest standards in the world. For this, two of the most powerful and precise monster machines in the world are used to manufacture and test it. It's a miracle that the SL5000 can be made, and installing it is also an unprecedented challenge. A project of this magnitude has once again shocked the world.
