China Daily - - BUSINESS -

Dong­fang Elec­tric Ma­chin­ery Co Ltd, a lead­ing Chi­nese elec­tric ma­chin­ery maker in South­west China’s Sichuan prov­ince, has de­vel­oped and com­pleted the run­ner for a mil­lion-kilo­watt gen­er­at­ing unit, the world’s largest in terms of ca­pac­ity. The com­pany de­liv­ered the huge run­ner, the core part of gen­er­at­ing unit, at the Bai­hetan hy­dropower sta­tion con­struc­tion site over the week­end. The run­ner has a di­am­e­ter of 8.62 me­ters and is 3.92 me­ters high. It weighs 353 met­ric tons. It took more than 100 techni- cians one year to com­plete the run­ner, seen as “the heart of power units.” The max­i­mum ca­pac­ity of a hy­dropower gen­er­at­ing unit stands at 800,000 kilo­watts. The Bai­hetan hy­dropower sta­tion is de­signed to have 16 do­mes­ti­cally-made gen­er­at­ing units each with a mil­lion-kilo­watt ca­pac­ity.
