| Siemens builds line for hydropower plant in China  Siemens Energy is constructing a gas-insulated high voltage line (GIL) with a total tube length of 3.2 kilometers for the Chinese hydropower plant "Jinping I" in the Liangshan Yi district of Sichuan province. Siemens is installing three three-phase GIL systems, each with a length of 350 meters, as a link between the machine transformers in the power plant cavern and the high voltage switchgear for connecting to the overhead line. The 305-meter high dam wall of the power plant is the highest structure of its kind in the world. As a result, the GIL has to bridge vertical sections about 200 meters long, which necessitated special design. The high voltage transmission system can transmit 3500 MVA of power at a voltage of 550 kilovolts (kV). The order was placed by Ertan Hydropower Development Company, Ltd., Chengdu. The GIL is scheduled to go into operation in mid-2012.Siemens Energy is constructing a gas-insulated high voltage line (GIL) with a total tube length of 3.2 kilometers for the Chinese hydropower plant "Jinping I" in the Liangshan Yi district of Sichuan province.
