10月28日，在安徽省铜陵县，安徽送变电工程公司的施工人员在270多米的高空作业。 On October 28,There in anhui province,Anhui conversion engineering company's construction personnel in more than 270 meters of aerial work.

    当日，由安徽送变电工程公司承建的“皖电东送”淮南至上海特高压交流输电示范工程长江南岸跨越铁塔封顶。 On that day,By anhui conversion engineering company of construction"To east anhui electric"Huainan to Shanghai uhv ac transmission demonstration project on the Yangtze river crossing tower capped.

    我国首条同塔双回路特高压交流输电工程——“皖电东送”工程西起安徽淮南，经皖南、浙北到达上海，线路全长656公里，共有1421座铁塔，整个工程计划2013年底建成投运。工程建成后，每年将能输送超过500亿度电，相当于为上海新建了6座百万千瓦级的火电站。 Our country first TongDa double circuit uhv ac transmission engineering --"To east anhui electric"Engineering west up anhui huainan,The southern anhui/Arrive in Shanghai for zhejiang province,Line (656 km),A total of 1421 seat tower,The whole project built by the end of 2013 is put into operation.After the completion of the project,Each year will be able to transport more than 50 billion KWH,For Shanghai is equivalent to the newly built six seat million kilowatt of thermal power station.

    目前，该工程已进入最为关键的跨越长江阶段，为此建设的跨越铁塔高达277.5米。该工程跨越长江长度约3公里，通过立于长江南北岸的两座输电塔直接放线跨越。由于采用的是两条回路都通过同一座输电塔进行跨越，线路自重超过一般线路两倍以上，对跨越铁塔的塔基牢固性、塔身稳定性的要求超过以往，属于世界同类塔中高度最高、施工难度最大的一项工程。新华社发（郑贤列 摄） At present,The project has entered into the most crucial phase across the Yangtze river,The construction of this crossing tower as high as 277.5 meters.The project across the Yangtze river length about 3 km,Through the south of the Yangtze river in the northern bank of the two transmission tower direct alignment across.Because use is two loop through the same seat transmission tower to cross,Line weight more than general line two times above,The crossing of the tower Kentucky soundness/Tower body stability requirements than ever,The world belongs to the same height of tower top/The biggest difficulty in construction of a project.The xinhua news agency hair(ZhengXian column perturbation)
