前 言
随着我国国民经济和电网建设的不断发展，我国的高压交流输电技术得到了迅速发展，目前，我国电网的最高运行电压等级从500kV发展到750kV。电网建设以科学发展观为指导，充分利用高新技术和先进设备，在加强现有电网技术改造和升级方面取得了较大的成果。许多新技术、新工艺和新材料正在得到广泛运用和大力推广，成为电网设计和建设中的重要组成部分。为了规范设计，统一标准，确保工程安全和工程造价合理，编制本规定。
本规定编制的指导思想是：贯彻电力建设基本方针，依靠科技进步和技术创新，认真落实安全可靠、先进适用、经济合理、环境友好的原则，体现设计方案的经济性、合理性。
本规定编制的技术原则：遵照DL/T 5092—1999《110～500kV架空送电线路设计技术规程》和参照Q/GDW 102—2003《750kV架空送电线路设计暂行技术规定》中的原则，并充分吸收规程颁发以来电力行业标准化、信息化研究推广应用的成果，在总结和分析的基础上编制而成。
本规定根据国家对环境保护的法律、法规，增设了环境保护章节。
本规定根据国家法规对劳动安全和工业卫生的要求，设置了劳动安全和工业卫生章节。
本规定根据电网建设中新技术、新工艺、新材料的应用，在路径、导线和地线、绝缘子和金具、杆塔结构等章节，增加了相关的内容。
本规定则体现了“基建为生产服务”的理念，认真研究生产运行提出的问题，在安全、经济、合理的基础上提出了适当的条文规定。
本标准由国家电网公司科技部归口。
本规定主要编制单位：国家电网公司、中国电力工程顾问集团公司、华东电力设计院。 本规定参加编制单位：西北电力设计院。
