CCTV “news broadcast” reported yesterday taizhou FengCheng merry 500 kv lines to wuxi Yangtze river crossing engineering caps the Eiffel Tower is a key project of national electric power development “much starker choices-and graver consequences-in planning – taizhou FengCheng to wuxi merry is an important part of the 500 kv transmission line project, located in the Yangtze river on both sides of the wuxi jiangyin port and taizhou jingjiang newbridge,It is the sixth high-grade power channel across the Yangtze River in Jiangsu province.The transmission steel tower 385 meters high, cross the Yangtze river distance of 2550 meters, in addition to the Eiffel Tower in 385 meters world record the highest power transmission tower, also in the crossing tower root size, elevator hoisting height, group tower derrick construction built seven data such as height in industry in the world, after builders successful capped more than six months of fighting.FengCheng, 500 kv melli Yangtze large span transmission project is China’s strategy of “north to south” the focus of the project, project to undertake jiangsu area after the operation of uhv calls, fully given new energy landscape, effectively improve the Yangtze river on both sides of the power grid interconnection, complementary each other aid ability, accelerate the development of Yangtze river delta integration is of great significance.Once completed, the Fengcheng-Meili 500-kilovolt transmission line will have a maximum transmission capacity of 6.6 million kilowatts, and will be able to transfer about 28.9 billion kilowatt hours of clean electric energy from the north bank of the Yangtze River to the south bank of the Yangtze River every year, meeting the daily electricity demand of about 8 million households.Know more why are you building a transmission tower this tall?All the time, the characteristics of jiangsu regional economic development are very obvious.According to statistics, in 2021, the annual electricity consumption in southern Jiangsu was 409.092 billion KWH, accounting for 57.61% of the province;The annual electricity consumption in northern Jiangsu is 150,876 million KWH, accounting for 21.25% of the province.South Jiangsu province is the load center of the whole Jiangsu province and even the Yangtze River Delta region.In 2021, the installed capacity of offshore wind power in Yancheng and Nantong alone has exceeded 10 million kilowatts.Most of the electric energy transferred to Jiangsu by uHV from shanxi, Inner Mongolia and other energy bases also landed in northern Jiangsu.Therefore, “Nortel south transmission” is more urgent.Why was the Tower built 385 meters across the Yangtze River?As we all know, the location of towers along the golden Waterway of the Yangtze River is controlled by the ecological red line, the protection distance at the foot of the Yangtze River, local planning and other factors.The Yangtze River spans 2550 meters, and the natural vertical curve of the cable will reach 256.8 meters.This is because the navigable height of a huge ship — 57.8 meters — must be set aside between the wire and the river.In addition to the safety distance, comprehensive error, span length of insulator string, safety height, tower head height, etc., the total height across the tower has reached an unprecedented 385 meters.So, how high is 385 meters?The tower is 128 stories tall, or 61 meters taller than the Eiffel Tower. After the tower is topped off, construction workers will start installing fittings and laying out lines across the river, which is expected to be completed by June 2022.
