Recently, the sea wind in Jiaxing, Zhejiang has gradually tightened, and the outline of Typhoon Bawei has become clearer on meteorological cloud maps. In the operation and inspection center of State Grid Jiaxing Power Supply Company, a race against time has begun. The repair vehicles are loaded with brand new tower materials and tools and heading towards the coastal line. They need to put on bulletproof vests for the criss crossing high-voltage iron towers before the storm arrives, guarding the gateway of the Yangtze River Delta energy artery.

Iron tower physical examination locks hidden dangers

State Grid Jiaxing Power Supply Company has officially launched a special action for wind resistant reinforcement of transmission lines. The operators did not blindly carry out construction, but strictly followed technical standards to conduct comprehensive physical examinations on key towers with long operating years and located at wind vents. 

From the subtle deformation of tower materials to the tightness of bolts, to the settlement of foundations, every detail is included in the inspection scope to ensure that hidden dangers are discovered and eliminated, and to improve the health level of equipment from the source.

Precise reinforcement enhances resilience

In response to the identified weak links, construction personnel quickly carried out precise surgical reinforcement. The bending and torsion resistance of the tower has been significantly enhanced by installing slant support, replacing high-strength bolts, pouring concrete slope protection and other measures. This kind of strong reinforcement is not limited to physical reinforcement, but is also supplemented by real-time monitoring methods to dynamically track the reinforced tower base, ensuring that the tower can stand steadily and withstand extreme wind loads.

Front defense builds a strong barrier

This proactive defense action marks a profound transformation of power grid operation and maintenance from passive rescue to front-line defense. The relevant person in charge of State Grid Jiaxing Power Supply Company stated that by consolidating the physical foundation of the power grid in advance, it can not only effectively resist the impact of Typhoon Bawei, but also lay a solid foundation for reliable power supply during the peak summer period in 2026. This proactive disaster prevention mode is becoming the new normal for China's power grid to cope with extreme weather.Editor/Gao Xue
