Post type cap and pin insulator, also called cap & pin post insulator or cap and pin stacks and units, is typically used on a sub base to achieve the desired electrical performance.
Post type cap and pin insulator application and features:
Cap and pin insulators have served the industry well since their introduction in 1911. These post insulators have provided strong, rigid mechanical support for bus runs, switches and other energized apparatus. Both their mechanical and electrical strength are derived by nesting porcelain shells between the metal cap and pin. Cap & pin insulators have excellent electrical performance under icing and polluted conditions. Their large, staggered diameters and large spacing between shells deter ice bridging. Their porcelain shell design also means that a large percentage of their leakage distance is protected, therefore providing a high contamination withstand voltage.
The post type cap and pin insulator has a basic design flaw. There is metal and cement internal to the porcelain. Replacing cap and pin stacks and units has become a serious problem because there is little domestic manufacturer of these station post insulators.
