Bushing may refer to: . Bushing (bearing), a type of plain bearing Bushing (electrical), an insulated device that allows a conductor to pass through a grounded conducting barrier
The use of resin (polymer, polymeric, composite) insulated bushings for high voltage applications is common, although most high-voltage bushings are usually made of resin impregnated paper insulation around the conductor with porcelain or polymer weather sheds, for the outdoor end and occasionally for the indoor end.
These bushings often take the form of an annular cylinder of flexible material inside a metallic casing or outer tube. They might also feature an internal crush tube which protects the bushing from being crushed by the fixings which hold it onto a threaded spigot. Many different types of bushing designs exist.
Split bi-material bushings: a metal exterior with an inner plastic coating A graphite-filled groove bushing. Plain bearings must be made from a material that is durable, low friction, low wear to the bearing and shaft, resistant to elevated temperatures, and corrosion resistant. Often the bearing is made up of at least two constituents, where ...
