Ceramic Insulator Definition

If the ceramic is glazed as zareba insulators are the glaze is only baked into the top layer.

Ceramic insulator definition.

It operates at above 33kv and overcomes the limitation of pin type insulator like the following. Once it s shaped it is fired between 2 100 to 2 300 fahrenheit. 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.

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. 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.

Ceramic is less expensive to produce than porcelain. A suspension type insulator protects an over headed transmission line like a conductor. 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.
