Ceramic Insulator Definition

Insulators used for high voltage power transmission are made from glass porcelain or composite polymer materials. It operates at above 33kv and overcomes the limitation of pin type insulator like the following. Generally it is made up of porcelain material that includes single or a string of insulating discs hanged over a tower.

Ceramic insulator definition.

What is suspension insulator. Insulators made from porcelain rich in alumina are used where high mechanical strength is a criterion. 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.

A suspension type insulator protects an over headed transmission line like a conductor. Ceramic insulators are ceramic materials used to insulate electrically conductive materials or temperature controlled enclosures. Look it up now. 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.

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 is less expensive to produce than porcelain. Ceramic is made of red brown or white porous clay.
