Chinese workers labor on the world's highest overhead power transmission tower line in Shannan city, Southwest China's Tibet Autonomous Region. Located along the "rooftop of the world", the transmission line reaches 5,548 meters in height and is also the longest HVDC line ever built at such an altitude. The 35-kilovolt power transmission line will be put into operation at the end of September this year. Photo: IC
