Ceramic Insulators Definition

Insulators used for high voltage power transmission are made from glass porcelain or composite polymer materials.

Ceramic insulators definition.

They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. If the ceramic is glazed as zareba insulators are the glaze is only baked into the top layer. 4 4 out of 5 stars 15. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material.

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. Link to other types of insulators.

Some elements such as carbon or silicon may be considered ceramics ceramic materials are brittle hard strong in compression and weak in shearing and tension. Zareba systems 027847 wp 5e single groove porcelain insulator with nails 25 pack. Look it up now. Similar to their glass counterparts porcelain insulators date back to before the civil war for telegraph wires.

Ceramic is made of red brown or white porous clay. Made of high strength calcium silicate these durable sheets withstand high temperatures and are often used in power generating applications. Ceramic is less expensive to produce than porcelain.
