Scope

This document specifies the terms and definitions, basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of anti-overturning high-voltage transmission line towers (hereinafter referred to as "towers"). This document is applicable to the design, production, inspection, and acceptance of anti-overturning high-voltage transmission line towers with a rated voltage of 110 kV to 750 kV, located in flat, hilly, or mountainous areas, and capable of withstanding loads such as wind loads, ice accretion, earthquakes, and line breaks. It is not applicable to special towers designed for extreme geological conditions (such as debris flows, strong earthquake zones, and deep soft soil areas) or extreme weather conditions (such as super-strong typhoons and extremely heavy ice accretion).
