Ceramic Insulator Definition

In the context of electrical insulation ceramic insulators are usually limited to the insulation of electrically conductive materials on an industrial or municipal scale.

Ceramic insulator definition.

Insulators used for high voltage power transmission are made from glass porcelain or composite polymer materials. What is suspension insulator. If the ceramic is glazed as zareba insulators are the glaze is only baked into the top layer. Ceramic is less expensive to produce than porcelain.

It operates at above 33kv and overcomes the limitation of pin type insulator like the following. Ceramic is made of red brown or white porous clay. Porcelain insulators are made from clay quartz or alumina and feldspar and are covered with a smooth glaze to shed water. Once it s shaped it is fired between 2 100 to 2 300 fahrenheit.

Insulators made from porcelain rich in alumina are used where high mechanical strength is a criterion. Generally it is made up of porcelain material that includes single or a string of insulating discs hanged over a tower. Ceramic insulators are ceramic materials used to insulate electrically conductive materials or temperature controlled enclosures.
