Composite post insulators include post type composite apparatus insulators and composite station post insulators. Post insulators are mainly used for equipment, Device or substations, such as plant construction, busbar supports. Composite station post insulators are used on stations & substations. Composite post insulators should be took tests of cantilever strength upright, tensile strength, compression strength, and torsional strength.

Standard: IEC 62231, ANSI C29.19
