补充资料：架空输电线路
| 架空输电线路 overhead line 用绝缘子将输电导线固定在直立于地面的杆塔上以传输电能的输电线路。它由导线、架空地线 、绝缘子串 、杆塔、接地装置等组成。导线由导电良好的金属制成，有足够粗的截面（以保持适当的通流密度）和较大曲率半径（以减小电晕放电）。超高压输电则多采用分裂导线。架空地线(又称避雷线 ）设置于输电导线的上方 ，用于保护线路免遭雷击。重要的输电线路通常用两根架空地线。绝缘子串由单个悬式（或棒式）绝缘子串接而成，需满足绝缘强度和机械强度的要求。每串绝缘子个数由输电电压等级决定。杆塔多由钢材或钢筋混凝土制成，是架空输电线路的主要支撑结构。架空输电线路在设计时要考虑它受到的气温变化、强风暴侵袭、雷闪、雨淋、结冰、洪水、湿雾等各种自然条件的影响，还要考虑电磁环境干扰问题。架空输电线路所经路径还要有足够的地面宽度和净空走廊。
