110（66）kV~500kV架空输电线路技术标准

1总则 1.1目的

为适应电网的发展要求，加强架空输电线路技术管理，保证输电线路的安全可靠运行，特制定本技术标准。 1.2依据

本标准是依据国家、行业和国际有关标准、规程和规范，并结合近年来国家电网公司输变电设备评估分析、生产运行情况分析以及设备现场运行经验制定。 1.3内容

本标准对架空输电线路的设计选型（运行选用）、订货、监造、出厂验收、包装运输、现场安装和现场验收等环节提出了具体的技术要求。 1.4适用范围

本标准适用于国家电网公司系统的110（66）kV?500kV交流架空输电线路。35kV交流架空输电线路和±500kV直流架空输电线路可参照执行。 2本标准适用的环境条件

2.1 本标准适用于I~IX级典型气象区和0~IV级污秽区的架空输电线路（以下简称“线路”），具体典型气象区和污秽分级标准参见附录A、B。 2.2 本标准适用于海拔高度不超过1000m地区的线路。

2.3 线路的设计应综合考虑气象、地形地貌、地质、环保、施工、运行、交通条件、综合造价等因素，做到安全可靠、经济合理、适当先进。

2.4 线路应尽量避开人口密集区、林区、不良地质地带、采矿（石）区、重冰区、重污秽区以及严重影响安全运行的其他地区，并应考虑线路路径与邻近公共设施，如通讯设施、机场、弱电线路、铁路、公路、航道等的相互影响。 3线路主要特征及设备分类 3.1主要特征

⑴电压等级 ⑵输送容量

⑶线路路径、路径长度 ⑷线路回路数 ⑸气象条件 最高气温（℃） 最低气温（℃） 覆冰气温（℃） 最大风速气温（℃）
