Five insulators
WebInsulators 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. Insulators made from porcelain rich in alumina are used where high mechanical strength is a criterion. WebPlastic, wood, glass and rubber are good electrical insulators. That is why they are used to cover materials that carry electricity. The plastic covering that surrounds wires is an electrical...

WebA string of six suspension insulators is used to support one conductor of a 66 kV, three-phase, overhead line. The air capacitance between each cap/pin junction and the tower is one tenth of the capacitance of each unit. Calculate the voltage across each insulator and the string efficiency. The most effective electrical insulators are: Rubber Glass Pure water Oil Air Diamond Dry wood Dry cotton Plastic Asphalt Other strong insulators include: Fiberglass Dry paper Porcelain Ceramics Quartz Other Factors That Influence Conductivity The shape and size of a material affect its conductivity.
