CCTV News: With the rise of temperature, the cooling load of air conditioning has significantly increased, and the electricity load of the power grid continues to increase. In order to ensure reliable power supply, power employees who are fighting in various places still adhere to their positions and fully guarantee the production and daily electricity consumption of the people.
State Grid Weifang Power Supply Company's Live Work Center employee Jie Weizeng: We will check and inspect protective clothing, drink some water, and prepare to go to work.
At 3 pm, the tester in the hands of the staff showed that the surface temperature had exceeded 39 ℃. Jie Weizeng and his colleagues also need to wear airtight protective clothing and start the afternoon live maintenance work.

State Grid Weifang Power Supply Company Live Work Center Staff Xie Weizeng: Safety measures in place, apply for equipotential work.
Yu Xin, an employee of State Grid Weifang Power Supply Company's Live Working Center, said: You can enter and pay attention to the distance between your face and the wires.
In such a high-temperature environment, it is a huge test of the physical fitness of the workers. The staff worked together in a space of less than 2 square meters at a height of 10 meters to carry out uninterrupted work and repair damaged wires. This operation lasted for nearly 40 minutes. When they returned to the ground, their protective suits were already soaked in sweat.

In Jining, Shandong, 239 substations, over 6690 kilometers of transmission lines, and 23000 kilometers of distribution lines are dotted with fully armed workers. They are on duty 24 hours a day, conducting special patrols under high temperatures to strengthen weak links in line operation. Since June this year, Shandong has dispatched more than 30000 personnel to carry out more than 8500 uninterrupted power distribution operations, effectively ensuring the safe and reliable supply of electricity during peak hours.
Outdoor construction workers work at high altitudes to ensure safety
Similarly, there are also a large number of power engineering construction workers who are braving high temperatures. At the construction site of the 220 kV Wenhua to Faku new transmission line project in Liaoning, construction workers have to brave high temperatures and climb more than 30 meters high towers to carry out wire installation operations.

The 220 kV Wenhua to Faku new transmission line project plans to build 178 new towers and 49.7 kilometers of transmission lines, which is a reinforcement project for the supporting grid structure of 4.8 million kilowatts of new energy transmission in Liaoning. After completion and operation, over 600000 kilowatts of new energy electricity can be connected to the Liaoning power grid, which will effectively enhance the supply guarantee capacity of the Liaoning power grid.
Zou Yaoxing, Project Manager of the 220 kV Wenhua to Faku New Line Project: In order to cope with high temperature weather, construction personnel are arranged to work in two time periods: 4:30 am to 10:30 am and 3:30 pm to 7:30 pm every day, and heatstroke prevention and cooling materials such as mineral water and Huoxiang Zhengqi water are timely distributed to ensure construction safety and progress.
New equipment provides cooling solutions for electric workers to relieve heat

It is the steadfastness of the vast number of power workers on the front line that enables the people to enjoy a cool summer. At the same time, some new equipment has also been distributed to these outdoor workers to alleviate the discomfort caused by high temperatures.
In recent days, the highest temperature in Shijiazhuang has exceeded 38 ℃, and the outdoor environment is hot and humid. At noon, in the Longgang community of Shijiazhuang, local power department live workers were carrying out equipment replacement work on the 10 kV line.
Wu Hao, Secretary of the Party Branch of the Live Work Center of State Grid Shijiazhuang Power Supply Company: This year, in addition to equipping outdoor workers with heatstroke prevention drugs, we have also added a new type of equipment - an "air-conditioned vest" to help everyone prevent heatstroke and cool down.

The newly equipped cooling equipment - the "air-conditioned vest" adopts cold liquid and eddy current technology, injecting cold liquid into the vest. The cold liquid transfers heat from the operator's back, chest, and other areas through the pipeline inside the vest, allowing live workers wearing full sets of insulation protective clothing to maintain a cool and comfortable state. Even in hot weather around 40 ℃, this clothing can maintain the human body within the range of around 30 ℃, and adding disposable refrigerant can effectively and continuously cool down for about 1 hour.
