Ceramic Insulator Definition

A suspension type insulator protects an over headed transmission line like a conductor.

Ceramic insulator definition.

What is suspension insulator. Ceramic is made of red brown or white porous clay. Insulators made from porcelain rich in alumina are used where high mechanical strength is a criterion. It operates at above 33kv and overcomes the limitation of pin type insulator like the following.

If the ceramic is glazed as zareba insulators are the glaze is only baked into the top layer. Insulators used for high voltage power transmission are made from glass porcelain or composite polymer materials. Generally it is made up of porcelain material that includes single or a string of insulating discs hanged over a tower. In the context of electrical insulation ceramic insulators are usually limited to the insulation of electrically conductive materials on an industrial or municipal scale.

Look it up now. Ceramic insulators are ceramic materials used to insulate electrically conductive materials or temperature controlled enclosures. Porcelain insulators are made from clay quartz or alumina and feldspar and are covered with a smooth glaze to shed water.
