What is porcelain insulators?

Porcelain insulators are made from clay, quartz or alumina and feldspar, and are covered with a smooth glaze to shed water. Insulators made from porcelain rich in alumina are used where high mechanical strength is a criterion. Porcelain has a dielectric strength of about 4–10 kV/mm.

Are porcelain insulators still used?

Because of these advantages, many utilities have switched from porcelain insulators to polyethylene insulators in the decades since their invention, but many are still using porcelain or just considering a switch.
