China News Service, Hangzhou, February 20th (Bao Mengni, Zhang Yue, Zhou Xiaoyu) On February 20th, State Grid Zhejiang Electric Power’s team to aid Hunan’s anti-ice and power supply team made a triumphant return. During the Spring Festival holiday, they drove against the traffic on their way home, rushing to the front lines of anti-ice rescue operations such as Pingjiang and Liuyang in Hunan to protect the lights of thousands of homes in foreign lands.
On the eve of the Spring Festival, a large-scale severe freezing rain weather struck Hunan. The process lasted for a long time, the rainfall intensity was high, the rain and snow phases were complex, and the freezing and snowstorms were superimposed. It became the strongest freezing process in the area since 2009. In some counties (cities, districts) in Changde, Yiyang, Yueyang and other places, the thickness of ice (frozen) on electric wires exceeds that in 2008. Rain, snow and freezing disasters have brought severe challenges to the safe operation of local power grid equipment.

On February 6, within just one day after receiving the instruction from the State Grid Corporation of China, State Grid Zhejiang Electric Power quickly assembled a support team of nearly 300 people, bringing more than 40 emergency repair vehicles, 8 emergency power generation vehicles, Five emergency support vehicles rushed to the rescue at starry night.
"There is no passable road on the mountain, and the emergency supplies do not have the conditions to enter the site." The relevant person in charge of the emergency repair team said that although most of the emergency repair team members had experience in ice rescue operations in 2008 and 2016, when they actually arrived at the scene, The harsh environment is beyond most people's imagination.
Due to the continuous freezing rain, the deep mountains were blocked by ice and snow, with thick layers of ice attached to the surface of all plants, and dense ice edges hanging from the power lines on the roadside. Trees in mountainous areas have fallen down, blocking the way into the mountains for inspection.
But the word "quick" stands out in the rescue operation. When the road was slippery and difficult to navigate, the emergency repair team crawled to patrol the line; when there was no road ahead, the team members opened a path; when vehicles got stuck in the mountains, everyone worked together to push them up the mountain. Emergency repair supplies and equipment were transported on shoulders and hands, and the inspection personnel opened more than 5,000 meters of mountain roads.
On February 10, the ice and snow melted, and all kinds of mechanized equipment were put in place. The emergency repair team operated an excavator to level the construction site, and introduced crawler cranes and crawler transport vehicles to complete the transportation of construction tools and some tower materials to improve the overall emergency repair efficiency. During the wiring construction, the team members used drones to deploy the guide ropes, which greatly shortened the wiring construction period. They also set up generators and lighting fixtures and carried out tower assembly operations overnight.

In the early morning of February 19, in Longtoujianshan District, Shegang Town, Liuyang City, Changsha, Hunan, with the completion of the last emergency repair task, the nerves of all team members who had been tense for more than ten days finally relaxed. Although they were unable to go home to celebrate the Chinese New Year, the emergency repairmen of State Grid Zhejiang Electric Power were very happy at the moment.
When I left, the mountains were covered with ice and snow, but when I came back, thousands of houses were lit with lights. Peace is their common expectation. (over)
