Porcelain post insulator are widely used in power systems as essential components that provide electrical insulation and mechanical support.
Application in Substation Systems
In substations, Ceramic post insulator are commonly referred to as station post insulators. These insulators have flanges on both sides, with bolt-fixed holes on the flanges for secure mounting. Station post insulators are fixed onto a base, and their top section is designed to support busbars.
Application in Transmission Systems
In transmission lines, post insulators are typically used as line post insulators. These insulators also feature a base for secure attachment to poles or crossarms. The head of the insulator has a groove for holding conductors. Some line post insulators are equipped with vertical or horizontal conductor clamps, with the type and orientation depending on their specific application.
