摘要
介绍了推广和应用输电线路典型设计的目的和主要设计条件,并按照输电线路电压等级、回路数、气象条件、导线截面、适用地形、铁塔型式和海拔高度等划分了36个模块、486种塔型,对杆塔规划、杆塔结构优化、主要技术特点等进行了详细说明：对输电线路典型设计综合效益进行了对比分析；最后介绍了输电线路典型设计下一步重点工作。
The purpose of spreading and applying the typical design of transmission line within the voltage grades from 110kV to 500kV and their main design conditions are presented. According to the voltage grades, number of transmission circuits, meteorological conditions, crosssectional area of wires, landforms and models of towers as well as attitudes of transmission lines, the typical design of transmission lines are divided into 36 modules and 486 types of towers. The layout of towers and optimization of tower structure, principal technological features of typical design are described in detail. The comprehensive benefit brought about by adopting typical design of transmission lines are analyzed and compared with the benefit brought about by design results with former individual design methods. Finally, the key tasks to be carried out in the next step are introduced.
