World's First 500-Megawatt Impulse Hydropower Unit's Water Distribution Pipe Completed and Delivered

On October 21, a major breakthrough was achieved in the field of hydropower as the water distribution pipe independently developed by Dongfang Electric Group was successfully completed and delivered. This marks a significant milestone in China's pursuit of high-head, large-capacity impulse hydropower technology.

On October 21, a major breakthrough was achieved in the field of hydropower as the water distribution pipe independently developed by Dongfang Electric Group was successfully completed and delivered. This marks a significant milestone in China's pursuit of high-head, large-capacity impulse hydropower technology.

The water distribution pipe, an impressive engineering feat, measures approximately 28 meters in length, 25.2 meters in width, and 4 meters in height. With a maximum outer diameter of about 3.9 meters and weighing a hefty 411 tons, it underwent a rigorous pressure test with a maximum pressure of 12.9 MPa. It is set to be utilized at the Datang Zhala Hydropower Station.

The Datang Zhala Hydropower Station project, recognized as a major technological equipment project by the National Energy Administration, holds a unique position as the only domestic project currently capable of developing and demonstrating the application of a 500-megawatt high-head large-capacity impulse unit. With its high head, large capacity, and high-altitude characteristics, it is one of the most complex ongoing hydropower projects in the world. It serves as a crucial engineering endeavor to fill technical gaps in giant impulse units within China's manufacturing sector.

The project will install two sets of single-unit capacity impulse hydropower generators at 500 megawatts each. Dongfang Electric Group, taking on a significant responsibility, has supplied one set that has successfully passed acceptance tests upon delivery. This achievement not only showcases the advanced capabilities of Chinese engineering companies but also paves the way for further innovation and development in the global hydropower industry.
