Ceramic insulator definition.

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. Insulators made from porcelain rich in alumina are used where high mechanical strength is a criterion. A suspension type insulator protects an over headed transmission line like a conductor. 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. What is suspension insulator. Ceramic is made of red brown or white porous clay. If the ceramic is glazed as zareba insulators are the glaze is only baked into the top layer.

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. Ceramic is less expensive to produce than porcelain.
