The project involved building new overhead tie lines between two 10 kV circuits, addressing the lack of interconnection at the line terminals. During construction, workers used insulated aerial lift trucks in coordination with manual operations to efficiently complete overhead line erection and tie switch commissioning, minimizing the impact on electricity use by nearby residents and businesses. Upon completion, the two branch lines will be interconnected at their terminals, significantly improving power supply reliability. (Text/Photos by Feng Qisheng and Wang Jiahui)
