The world's largest wind turbine, made in China, what's the big deal?

China's giant wind turbine SL5000 ranks first in the world, and China independently develops and manufactures it, with only two in the world. This is the largest single wind turbine ever, which was independently developed by China Company. It not only has complete intellectual property rights, but also leads the world in technology.

SL5000 has a huge fuselage and can take off and land helicopters in the cabin. Only the blade diameter reaches 128 meters, and the height of the wind wheel exceeds 40 stories. The design life is about 20 years. In order to ensure that there are no problems in practice, all kinds of strict and precise tests are carried out. It took four months to test the blade, which was subjected to the strongest force in nature and vibrated 5 million times. The simulated service life is 20 years, and it is still intact. The bearing of the fan is the most easily damaged part, so the bearing of SL5000 needs to challenge the highest standard bearing in the world. For it, the two most powerful and accurate machine monsters in the world are used to make and test it. It is a miracle that SL5000 can be manufactured, and its installation is an unprecedented challenge. Such a huge project shocked the world again.
