CHONGQING, Sept. 13, 2022 (Xinhua) -- After a 13-day campaign, the cross-Yangtze River wiring operation for the Baihetan-Zhejiang 800 kv ultra-high voltage direct current (UHVDC) transmission line project concluded successfully on Tuesday. The 2,140-kilometer line, whose construction kicked off in October 2021, winds its way through Sichuan, Chongqing, Hubei, Anhui and Zhejiang. It is expected to be fully built by the end of September, and operational by November this year. Celebrated as one of China's "power highways," this line is also an important part of the country's west-to-east power transmission program.
