Current record value
The line runs from the Changji converter station in Xinjiang to the Guquan converter station in Xuancheng, Anhui, crossing Gansu, Ningxia, Shaanxi and Henan, with a total route length of 3,293 km.
It is rated at ±1,100 kV with a transmission capacity of 12,000 MW; full-voltage transmission began in January 2019, making China the first country able to deliver gigawatt-scale power over 3,000-5,000 km.
The project is also described as the world's largest-capacity and longest-distance UHVDC transmission project.
The record conclusion has sufficient verification support.
