Line post insulator is utilised in switchgear to support bus-bars in transformer sub-station yards as well as breakers and capacitor banks. It encounters compression, torsion, and bending stresses during usage. In addition to this, the said product has a number of advantages over ceramic and glass insulators, such as excellent performance in contaminated environments, light weight, simplicity of handling, maintenance-free operation, and significantly lower cost, among others. Line post insulator is an electrical equipment which is used for holding and separating electrical conductors while preventing current flow through them. It comes in different finishes and sizes.
