World’s first transmission line under the Yangtze river
Enabling clean energy to be transmitted from West to East China via 1,000-kilovolt gas-insulated lines. Due to China’s large geographic size, power sources are mostly located away from cities. Consequently, electricity must travel several hundreds, or even thousands, of kilometers to reach consumption points. For this purpose, ultra-high-voltage (UHV) transmission technologies are used to deliver large amounts of power across long distances and with lower energy losses.
