Hainan Changjiang Nuclear Power Unit 4 500kV Reverse Power Transmission Successfully Completed
On August 19, 2026, the 500kV reverse power transmission of Unit 4 of the Hainan Changjiang Nuclear Power Phase II Project was successfully completed, marking another major milestone in the engineering construction of the unit. The 500kV reverse power transmission operation lasted approximately 15 hours. Throughout the power receiving process, equipment operated stably, all parameter indicators were excellent, protection devices acted accurately without error, and system live switching proceeded smoothly, fully achieving the established goal of successful power reception on the first attempt. The realization of this milestone fully verified that the design, manufacturing, and installation quality of the 500kV main switchyard, main transformers, high-voltage auxiliary transformers, and related auxiliary systems of Unit 4 all met the required standards. The Hainan Project Department of CNNC Engineering coordinated design, procurement, construction,...
