Scope
This document specifies the altitude classification, correction methods, and external insulation levels for AC power transmission and transformation equipment in high-altitude areas. This document applies to the external insulation configuration and equipment selection of AC power transmission and transformation equipment in high-altitude areas of 5,500 m and below, with voltages ranging from 110 kV to 750 kV. This document does not address the configuration of external insulation under special weather conditions such as ice accretion, snow accumulation, and heavy rainfall.
