Research on the Standardization Scheme of Transmission Line Insulator Fitting Strings Based on Integrated Universal Design

This article proposes the selection, design and parameters of insulator strings for integrated universal design transmission line fittings, provides reference values for the strength of insulator strings used in 35kV~750kV transmission lines, and puts forward technical requirements for fitting design. By stipulating the matching and connection design of insulators and fittings, as well as the design of hanging points for fitting strings, a standardized scheme for fitting insulator strings of transmission lines at various voltage levels from 35kV~750kV was proposed.
