China's key ultra-high voltage (UHV) transmission project was put into use Thursday, sending clean power all the way from northwest China's Xinjiang Uygur Autonomous Region to central and east regions. The Suzhou-Nantong pipe rack project, a key part of it, puts 1,000-kilowatt UHV lines into six airtight pipelines which cross China's longest river, the Yangtze River via a 5,468-meter underwater channel.
