220kV紧凑型铁塔结构设计应用

摘要

The compact--type tower can be used in urban transmission lines for its reduction of line corridors and optimal land utilization. In the pa- per, the design plan was presented and the L--shaped insulator strings of insulators was also introduced. The conclusions can provide references for the design of overhead transmission lines in the suburban areas.%紧凑型铁塔具有根开小、塔头尺寸小、占用走廊小的特征，可满足城市输电线路走廊拥挤地区的线路工程应用。本文介绍紧凑型铁塔的L型绝缘子串应用、塔身结构设计优化与材料选用。提出的建议可以为城郊线路工程设计提供参考。
