Good news is once again spreading along the rushing Dadu River, as a high-altitude hydropower station has successfully connected all its units to the grid. Harbin Electric Corporation's self-developed equipment supports the supply of green electricity to the southwest. On June 20, 2026, the last unit of the Daduhe Jinchuan Hydropower Station, developed and manufactured by Harbin Electric Corporation, was successfully connected to the grid, and all units of the power station were put into operation, providing new support for the supply of clean energy in Southwest China. After the four units were put into operation successively, the equipment was perfectly adapted to the high-altitude river environment. The core temperature control indicators such as bearings and stator windings operated smoothly, and the equipment operated in excellent condition, stably outputting clean water and electricity from the plateau.

Jinggong Machinery is adapted to high-altitude working conditions

The Jinchuan Hydropower Station is located in the upper reaches of the Dadu River in Jinchuan County, Aba, Sichuan Province. It is invested and developed by the National Energy Group and is the sixth cascade hydropower station on the main stream of the Dadu River. The total installed capacity is 860000 kilowatts, equipped with four 215000 kilowatt mixed flow water turbine units. The entire set of generator supporting equipment is supplied by Harbin Electric Power Co., Ltd. During the project construction period, the enterprise strictly adheres to the standards of precision manufacturing, integrates refined control into all aspects of research and development, production, assembly, and commissioning, and relies on strong capabilities throughout the entire process to create high-quality hydropower equipment.

In the research and development stage, enterprises have made precise breakthroughs in adapting to high-altitude environments: they continue to use mature mixed flow unit designs, optimize electrical parameters, structural strength, and bearing lubrication systems, improve insulation configurations for high-altitude environments in western Sichuan, and ensure long-term stable and efficient operation of the units; Strictly control the entire production process, coordinate material procurement, processing and manufacturing, and factory inspection, complete the production acceptance of core equipment in advance, and ensure the timely progress of the project; During the on-site stage, professional technical personnel will be stationed around the clock to overcome high-altitude hypoxia and low temperature environments, work together with various units to synchronously complete unit installation and commissioning, and quickly handle various technical issues.
