On January 12, 2022, the tallest transmission tower in the world with a height of 385 meters was successfully capped in Jiangsu.

The tower is an important part of the 500 kV transmission line project from Taizhou Fengcheng to Wuxi Meili, a key project of the National Electric Power Development "Thirteenth Five-Year Plan". The sixth high-grade power channel in Jiangsu that crosses the Yangtze River.

"The project needs to cross the Yangtze River. In order not to affect shipping, we initially planned to build a 400-meter-high tower. Finally, after dozens of optimization and design improvements, the height was finally determined at 385 meters, so that all types of ships on the river can be safe and stable. Passed.” According to Chen Songtao, Construction Department of State Grid Jiangsu Electric Power Co., Ltd., during the construction process, a series of world records such as total weight and foundation depth were also created, setting up super-high power transmission towers and long-distance spanning for related fields in the world. China's experience in tower construction and other aspects.

The Fengcheng-Meili 500 kV transmission line project starts from the Fengcheng 500 kV Substation in Taizhou and ends at the Wuxi Meili 500 kV Substation. The 500 kV line is newly built and renovated 178.1 kilometers, which is the most technically difficult 500 in the history of my country's power construction. kV cross-river interconnection transmission project.

"After the tower is capped, we will also carry out constructions such as the installation of fittings and wiring across the river. It is expected that the project will be completed in June 2022." Chen Songtao said.

After the completion of the 500 kV transmission line project from Fengcheng to Meili, the maximum transmission capacity will reach 6.6 million kilowatts, and about 28.9 billion kWh of clean electricity can be sent from the north bank of the Yangtze River to the south bank of the Yangtze River every year, meeting the daily electricity consumption of about 8 million households need.Editor/Ma Xue
