Insulating electrical
Elektrisk isolator er en enhet beregnet for elektrisk isolasjon og mekanisk innfesting av utstyr eller ledere som er gjenstand for elektriske potensialforskjeller. Isolatorer skal hindre strømgjennomgang, derfor velges materialer der indre elektrisk ladninger ikke flyter fritt, og som ikke fører strøm under påvirkning av et elektrisk felt gjennom stoffet. NettetThe electrical insulation of the field winding must isolate the conductors from the rotor body which is at ground potential, must separate adjacent turns within a coil, and must …
Insulating electrical
Did you know?
An electrical insulator is a material in which electric current does not flow freely. The atoms of the insulator have tightly bound electrons which cannot readily move. Other materials—semiconductors and conductors—conduct electric current more easily. The property that distinguishes an insulator is its resistivity; … Se mer Electrical insulation is the absence of electrical conduction. Electronic band theory (a branch of physics) explains that electric charge flows when quantum states of matter are available into which electrons can be excited. This … Se mer The most important insulation material is air. A variety of solid, liquid, and gaseous insulators are also used in electrical apparatus. In smaller transformers, generators, … Se mer Often a broadcasting radio antenna is built as a mast radiator, which means that the entire mast structure is energised with high voltage and must … Se mer A flexible coating of an insulator is often applied to electric wire and cable; this assembly is called insulated wire. Wires sometimes don't use an insulating coating, just air, when a solid (e.g. plastic) coating may be impractical. Wires that touch each other produce cross … Se mer Conductors for overhead high-voltage electric power transmission are bare, and are insulated by the surrounding air. Conductors for lower voltages in distribution may have some insulation but are often bare as well. Insulating supports are required at the … Se mer • Electronics portal • Stephen Gray – English physicist • Dielectric material • Electrical conductivity Se mer NettetInsulating materials are used in electrotechnical and electronic applications for electrical insulation. They are also used as mechanical protection and serve, among other things, as anti-skid protection for machine processing and increase operational safety.
