Mica paper insulations for conductors and cables

Abstract

The use of mica paper as insulation on magnet wires for high-voltage machines and traction motors is possible. The insulation is mechanically sufficiently strong enough for producing any kind of formed coils. The main advantages of mica paper covered magnet wires are the good dielectric properties and the corona resistance of the insulation. Certain types of mica paper tapes can also be used as cable insulation which belongs to the thermal class H. The cable insulation is resistant against moisture, mineral oils, corona, radiation and has excellent dielectric properties. In case of fire the mica paper covered cable is not producing any poisonous gases. This type of cable is suitable for leads in rotating machines of all kind, for power and auxiliary circuits in electrical vehicles, vessels, nuclear power stations, oil refineries etc.
