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.

If the ceramic is glazed as zareba insulators are the glaze is only baked into the top layer. 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. Insulators used for high voltage power transmission are made from glass porcelain or composite polymer materials.

Porcelain insulators are made from clay quartz or alumina and feldspar and are covered with a smooth glaze to shed water. Generally it is made up of porcelain material that includes single or a string of insulating discs hanged over a tower. Insulators made from porcelain rich in alumina are used where high mechanical strength is a criterion. Look it up now.

A suspension type insulator protects an over headed transmission line like a conductor. Once it s shaped it is fired between 2 100 to 2 300 fahrenheit. On a hilltop at the edge of town a bunch of drunken hunters were target shooting at the ceramic insulators on bishkek s primary high voltage lines this painting portrays in great detail a skeleton like electrical power transmission tower with dozens of identical ceramic insulators.
