Post Porcelain Insulators

Porcelain post insulators are usually an important part of the transformation equipment in power stations and substations, playing the role of supporting wires and insulating them. Porcelain insulators generally refer to insulators whose insulating parts are made of electrical ceramics, which electrical ceramics are usually baked from quartz, feldspar, and clay. The surface of porcelain parts of porcelain insulators is usually covered with enamel, so as to improve its mechanical strength, waterproof infiltration, and increase surface smoothness. 

Among all kinds of insulators, porcelain insulators are the most commonly used. Compared with glass insulators, ceramic insulators have the advantages of good insulation performance, weather resistance, heat resistance, and flexible assembly, so porcelain insulators are widely used in lines of various voltage levels. Relying on their excellent properties such as high resistivity, high dielectric strength, good mechanical properties, and good heat dissipation and insulation capabilities in humid and corrosive environments, ceramic insulators have become the most commonly used materials in power transmission and distribution systems. The two indicators of dielectric strength and mechanical strength are also the two most important decisive properties that must be considered in the production of high-quality porcelain insulators.
