架空输电线路的设计标准

[中文适用范围]： 指定源自基于可靠性的设计原则的架空线路的负载和强度要求。该要求适用于45kV及以上线路，但也可适用于标称电压较低的线路。设计标准 [外文原描述]： Specifies the loading and strength requirements of overhead lines derived from reliability based design principles. The requirements apply to lines of 45 kV and above, but they can also be applied to lines with a lower nominal voltage. The design criteria apply to new lines, however many concepts can be used to address the reliability requirements for refurbishment and uprating of existing lines. Detailed design of line components such as towers, foundations, conductors or insulators are not covered in this document.
