This standard specifies the correction method for the pollution withstand voltage and unified creepage distance of disc-shaped suspension insulators used in AC and DC transmission lines with nominal voltages higher than 1000V under pollution conditions in high-altitude areas. This standard is applicable to disc-shaped suspension insulators in areas with an altitude of 1000m-5500m. The correction method for the pollution withstand voltage and unified creepage specific distance of pillar insulators and bushings can refer to this standard.
