摘要
特高压线路的铁塔重量大、铁塔高、横担长、结构复杂。介绍根据不同的塔型、地形和交通状况,选择合适的组塔方案,配备合适的组塔抱杆,并探讨内抱杆组立铁塔施工技术、施工工艺、受力计算和工器具选择。
The tower of the extra high voltage （EHV） transmission line is heavy, tall, and it has longer cross arm and complex structure. This paper mainly introduces the choice of the proper schemes for assembly tower and adequate gin pole according to different type oftowers, topography and transportation condition. It describes that tower construction technique, process, strength calculation and apparatus selection by using the internal gin pole.
