Recently, CEEDI’s Inspection, Testing and Evaluation Center successfully completed the inspection work of the Tibet Networking Project. It is the most challenging power transmission and transformation project on the plateau with the highest altitude in the world, and also a super project with the largest span in the most complex natural conditions that challenging survival limit.

The project includes two parts: one is the Tibet Central Area and Changdu Power Grid Networking Project and the other is the power supply project of the Lhasa-Linzhi Section of the Sichuan-Tibet Railway. It starts from Mangkang County, Changdu City, Tibet, and ends in Sangri County, Shannan City, Tibet. Across three cities and ten districts and counties of Tibet, the project builds and expands 16 substations, lays 2,738 kilometers of overhead lines and erects 3410 iron towers with the total investment of 16.2 billion RMB Yuan. Especially, the 500 kV transmission tower at Dongdashan located at an altitude of 5,295 meters, and the 500 kV substation at Mankang of 4,295 meters and both of them break the records in the world.
