Porcelain insulators are a type of electrical insulator made of porcelain or ceramic materials. They are used in a variety of electrical applications to prevent electrical current from flowing across conductive materials or to separate conductive parts.
Porcelain insulators have excellent electrical and mechanical properties, making them ideal for high voltage and high-temperature applications. They can withstand high temperatures without losing their insulating properties, making them ideal for use in applications where heat is a concern.
Porcelain insulators are commonly used in power transmission and distribution systems, as well as in surge protection equipment and electronics. They are also used in heavy-duty electrical equipment, such as transformers and generators.
