China has finished construction of a 4,197-km extra-high voltage power transmission loop around the Tarim Basin, home to the country's largest desert, marking a major infrastructure milestone in southern Xinjiang Uygur autonomous region.

The final section of the 750-kilovolt (kV) loop, now the country's largest of its kind, was connected on Sunday, capping a 15-year project involving nine substations and nearly 10,000 steel towers, according to a subsidiary of State Grid Xinjiang Electric Power Co Ltd, which constructed the project.

The transmission line passes through extreme terrain, from the shifting sands of the desert to the high altitudes of the Kunlun Mountains.

Chen Lin arrived in March this year at the southern edge of the Taklimakan Desert, where he, side by side with over 40 colleagues, accomplished part of the transmission line construction work despite sandy gusts and scorching temperature.
