特高压交流输电系统 第202部分：特高压交流输电线路设计

[中文适用范围]： IEC 63042的这一部分为交流输电系统最高电压超过800 kV的架空输电线路的设计提供了通用规则，以便为预期用途提供安全性和正常功能。本技术规范旨在给出主要 [外文原描述]： IEC TS 63042-202:2021(E) provides common rules for the design of overhead transmission lines with the highest voltages of AC transmission systems exceeding 800 kV, so as to provide safety and proper functioning for the intended use. This technical specification aims to give the main principles for the design of UHV AC overhead transmission lines, mainly including selection of clearance, insulation coordination and insulator strings design, bundle-conductor selection, earth wire/optical ground wires selection, tower and foundation design, environmental consideration. The design criteria apply to new construction, reconstruction and expansion of UHV AC overhead transmission line.
