Dongfang Electric Machinery Co., Ltd, DEC's subsidiary which is located in southwest China's Sichuan Province delivered this gigantic runner, at the Baihetan hydropower station construction site on Jan 12, 2019. DEC has developed and completed the manufacturing of the runner for a million-kilowatt generating unit, the world's largest in terms of unit capacity.
The runner has a diameter of 8.62 meters and is 3.92 meters high. It weighs 353 tons. It took more than 100 technicians over one year to complete the runner, seen as "the heart of power units." The Baihetan hydropower station is designed to have 16 domestically-manufactured generating units each with a million-kilowatt capacity. It will be the second largest hydropower station after the Three Gorges project in terms of total installed capacity.
The delivery of the runner will guarantee the commissioning of the first unit for the Baihetan station in 2021 as scheduled.
