China’s giant wind turbine SL5000 is the world’s largest. It is independently developed and manufactured by China. There are only two units in the world. This is the largest single 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.
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 high. The design life is about 20 years. In order to ensure that no problems will occur in practice, various rigorous and precise tests were carried out on it. The test of the blades alone took 4 months to allow them to withstand the strongest force of nature. It vibrated 5 million times and was still intact after simulating a service life of 20 years. The bearings of wind turbines are the most vulnerable parts, so the bearings of the SL5000 need to challenge the highest standards in the world. For it, two of the most powerful and precise machine monsters in the world are used to manufacture and test it. It is a miracle that SL5000 can be manufactured. Its installation is also an unprecedented challenge. Such a huge project once again shocked the world.
