Popular Science Classroom | How does Xinjiang recharge the entire country?

Starting from the Zhundong (Changji) converter station in Xinjiang, this energy artery crosses the vast Gobi Desert, climbs over the majestic Tianshan Mountains, winds along the historic Hexi Corridor, and finally crosses the surging Yangtze River to reach the Xuancheng (Guquan) converter station in Anhui, realizing the magnificent leap of green electricity from the border to the Central Plains. The 3,293-kilometer line is not only a conquest of physical distance, but also a transmission of technology and green dreams.

The rated voltage is as high as ±1100 kV, and the rated power is astonishingly 12 million kilowatts, which means that it has the powerful ability to light up a 9-watt high-brightness LED bulb for each of the 1.4 billion Chinese people at the same time, injecting inexhaustible power into the prosperity and development of East China. Even more remarkable is that the annual delivery of more than 60 billion kWh of clean energy has not only greatly alleviated the energy pressure in East China, but also reduced coal transportation by 30.24 million tons, effectively reduced smoke emissions by 24,000 tons, sulfur dioxide by 149,000 tons, and nitrogen oxides by 157,000 tons, making an indelible contribution to the battle to protect the blue sky.

However, this is just the tip of the iceberg of China's many "super engineering" miracles. In this ancient and vibrant land, natural resources such as wind, light, and water are being transformed into a steady stream of green energy, and countless shocking but little-known engineering stories are waiting for us to discover, interpret, and spread.
