State Grid Zhenjiang completes first non-outage line renovation

At a 400-volt line renovation site in Jurong, a county-level city in Zhenjiang, Jiangsu province, a volunteer service team from State Grid Jiangsu Electric Power carried out the city's first low-voltage non-outage line renovation on June 3.

Unlike traditional low-voltage renovations that require power outages, this operation used a temporary bypass power supply system and a low-voltage generator truck as a backup, ensuring uninterrupted power for users.

The team captain said that the renovation coincided with the critical pre-harvest period for summer grain. The line serves 50 mu (3.33 hectares) of winter wheat fields and 22 farming households.

Traditional renovation would have required a three-to four-hour power outage, halting farm machinery debugging and grain drying, thereby delaying the summer harvest.

Next, State Grid Zhenjiang is planning 72 similar line renovations in preparation for summer grain harvesting, autumn irrigation, and specialty planting and breeding, further securing the power supply.
