LIAOCHENG, China, Nov. 11, 2024 /PRNewswire/ — On November 11, Pang Jinhu and Xue Ruiguo, employees of State Grid Liaocheng Power Supply Company, carried out inspections of 44 sets of “coal to electricity” supporting grid equipment in 12 villages along the 10kV Jinzhao line in Liaocheng City, Shandong Province.

After inspecting the line and equipment, Pang Jinhu sent a message in the “Warm winter” wechat group of Liaocheng Power Supply Company: the temperature of the 10 kV Jinzhao line equipment is normal and the line operating environment is normal. After seeing the information, Zhu Jianfeng, a staff member of the power supply service command center of the company, checked the real-time load current of the Jinzhao line and the maximum load of the distribution transformer through the power supply service command system. After confirming that there is no abnormality, he continued to wait for feedback from other on-site inspection personnel.
