State Grid Yulin Power Supply Company gave full play to the role of the "multi-dimensional inspection" system and organized line operation and maintenance personnel to prepare for de-icing and ice removal through online monitoring and video surveillance devices. Additionally, it employed the smart combination of "human inspection + drone inspection" to inspect key sections in an all-round way, including dense transmission channels and overhead lines crossing roads, railways and rivers for an accurate understanding of the operational status and health of the equipment.

Zhaochuan Power Supply Station of the State Grid Shannan Power Supply Company conducted nighttime inspections for potential hazards on the 10 kV power lines and in heavily overloaded substations in its jurisdiction. During the peak electricity consumption period at night, its workers focused on checking for any damage to porcelain insulators, signs of looseness, overheating or breakage in switch wires, transformers and other equipment contacts, as well as whether transformers were operating under overload conditions. These efforts are for ensuring a reliable electricity supply for the residents.
