Jinsha hydropower station is equipped with four sets of 140 MW Kaplan turbine generator units with a total installed capacity of 560 MW. The runner is the core of hydro generator, which is called the “heart” of the unit. The runner of Jinsha hydropower station is the largest Kaplan turbine runner under construction in the world, with a diameter of 10650 mm and a height of 7804 mm. The overall lifting weight is about 805 tons and the lifting height is about 19014 mm. Therefore, it is very difficult to hoist.

The relevant person in charge of chuanneng Panzhihua company said that it would continue to play the leading role of the owner to ensure the realization of the generation target of the first unit by the end of November.
