Ceramic insulators definition.

Ceramic is less expensive to produce than porcelain. 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. Similar to their glass counterparts porcelain insulators date back to before the civil war for telegraph wires.

Zareba systems 027847 wp 5e single groove porcelain insulator with nails 25 pack. In north america glass was always the predominate material for communications insulators but porcelain has become the standard for power distribution due to its greater strength and surface resistance. Abrasion resistant rigid calcium silicate insulation sheets. Made of high strength calcium silicate these durable sheets withstand high temperatures and are often used in power generating applications.

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. Strain insulator ceramic insulator oval shaped nsn. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. Insulators used for high voltage power transmission are made from glass porcelain or composite polymer materials.
