The construction of the Yellow River section of the extra-high voltage circuit connecting Hami in the Xinjiang Uygur autonomous region and Zhengzhou in Henan province was completed on April 16, 2013. It is the first extra-high voltage line operating over the Yellow River.

Built by State Grid Corporation of China (State Grid), the 2,210-kilometer Hami-Zhengzhou line was the longest extra-high DC line transmitting the highest level of voltage in the world at that time.

The section crossing the Yellow River was the most difficult and important part. The span transmission tower is 147.1 meter tall and each of the eight wires is 3.9-kilometer long and weighs 20-tons. The work was equal to pulling 100 cars across the river from a 50-floor high location.
