This week China started work to build world’s first 1,100 kilovolt direct current electricity transmission line. The 1,100kv DC Line will start from northwest China’s Xinjiang Uygur Autonomous Region, connecting Gansu Province, Ningxia Hui Autonomous Region, Shaanxi Province, Henan Province and Anhui Province. The whole length will be over 3,300 kilometers. When finished in 2018, its transmission capacity will be 12 million kilowatt.
This is a power line with the highest voltage, biggest transmission capacity, longest distance and the latest technology in the world. The 1,000 kilovolt ultrahigh AC transmission line project will reduce coal consumption by 9 million tons and carbon dioxide by 26.9 million tons. Another ultra-high voltage AC transmission lines are now under live-line operations in Tianjin, China.
