  • [Breakthrough from zero in the data of full altitude gradient transmission test]
  • On October 19, 2026, China Electric Power Research Institute completed the in-situ test of corona effect of ultra-high altitude conductors at the 5000m altitude test site in Anduo, Xizang. This experiment fills the gap in data for ultra-high altitude transmission tests and marks the first time in China that key parameters such as corona initiation voltage, corona loss, audible noise, and radio interference of conductors have been systematically obtained under a gradient from plain to 5000 meters at all altitudes.Editor/Gong Ziwei
