This operation overcame the limitations of single-vehicle work through an innovative approach. By applying advanced live-line work techniques, the company ensured, to the greatest extent possible, that residents’ daily lives and production at local enterprises continued in an orderly manner. The operation provides strong support for ensuring a reliable power supply during the summer peak period and contributes to the stable functioning of the local economy. (Text and photos by Cheng Gang)
