ActiveComposite string insulator units for overhead lines with a nominal voltage greater than 1 000 V― Part 2：Dimensions and characteristics
标称电压高于1 000V 的架空线路用复合绝缘子串元件 第2部分：尺寸与特性
Application Summary AI generated
This standard specifies the dimensions and electrical/mechanical characteristics of composite string insulator units used in overhead power transmission lines operating above 1,000 V. It is applied by manufacturers and utilities to ensure interchangeability and consistent performance of insulators in high-voltage networks. The standard is critical for design, procurement, and testing of insulators in electric power systems, particularly for transmission lines requiring reliable insulation under environmental stress.
