Recently, the first set of units in Wudongde hydropower station on Jinsha river, with an investment of more than one-hundred-billion Yuan, have been put into operation for power generation. In the construction of the world-class enormous hydropower project, SINOMACH-HE has contributed actively to the operation of this project with strong extreme manufacturing ability and multiple key technical breakthroughs.

Erzhong Equipment, the manufacturing subsidiary of SINOAMCH-HE, has been a major parts provider for the electric generating unit of Wudongde hydropower station, responsible for R&D of upper crown, lower ring, blade, main shaft of water turbine, main bearing of generator. With high technical and quality demands, the huge dimension and heavy weight of upper crown and lower ring posed huge challenges to Erzhong Equipment due to its manufacturing of this structure for the first time. At last, Erzhong Equipment accomplished the task with great success after tiding over a series of difficulties.

The picture above is about the material mixing of 280-ton stainless upper crown for Wudongde hydropower station in the steelmaking plant of Erzhong Equipment.
