What is a Porcelain Insulator?
A Porcelain Insulator is a ceramic electrical insulating device used to support electrical conductors while preventing current leakage between energized conductors and grounded structures. These insulators are widely used in overhead transmission lines, electrical substations, switchgear panels, transformers, railway electrification, distribution systems, and industrial electrical installations because of their excellent dielectric strength, superior mechanical durability, and long operational life.
Porcelain remains one of the most trusted insulating materials for medium- and high-voltage power systems due to its excellent resistance to moisture, ultraviolet radiation, corrosion, temperature variation, and environmental pollution.
