China aims ultra-high

China has begun work on the world’s first 1,100kV direct current electricity transmission line. The line will stretch from northwest China’s Xinjiang Uygur autonomous region, connecting Gansu province, Ningxia Hui autonomous region, Shaanxi province, Henan province and Anhui province.

“Its nominal voltage is 37.5 percent higher than those with an 800kV nominal voltage, and the transmission capacity is 50 percent more. We also increased the transmission distance from 2,000 to 3,000 kilometers.” A 1,000kV ultra-high voltage AC transmission line is in progress in Tianjin, to deliver energy from Inner Mongolia to Tianjin, Hebei and Shandong province. The project is expected to be in operation by the end of October 2016.

When completed the 3,300km line will have a transmission capacity of 12million kilowatts.

Chen Weijiang, a researcher at the Chinese academy of sciences, said the systemwill be the first to adopt the 1,100kV voltage.
