enameled copper wire
not, in fact, coated with either a layer of enamel paint nor with vitreous
enamel made of fused glass powder. Modern magnet wire typically uses one to four
layers (in the case of quad-film type wire) of polymer film insulation, often of
two different compositions, to provide a tough, continuous insulating layer.
Magnet wireinsulating films use (in order of increasing temperature range)
polyvinyl formal (Formvar), polyurethane, polyamide, polyester,
polyester-polyimide, polyamide-polyimide (or amide-imide), and polyimide.
Polyimide insulated magnet wire is capable of operation at up to 250 °C. The
insulation of thicker square or rectangular magnet wire is often augmented by
wrapping it with a high-temperature polyimide or fiberglass tape, and completed
windings are often vacuum impregnated with an insulating varnish to improve
insulation strength and long-term reliability of the winding.
coils are wound with wire coated with at least two layers, the outermost being a
thermoplastic that bonds the turns together when heated.
types of insulation such as fiberglass yarn with varnish, aramid paper, kraft
paper, mica, and polyester film are also widely used across the world for
various applications like transformers and reactors. In the audio sector, a wire
of silver construction, and various other insulators, such as cotton (sometimes
permeated with some kind of coagulating agent/thickener, such as beeswax) and
polytetrafluoroethylene (Teflon) can be found. Older insulation materials
included cotton, paper, or silk, but these are only useful for low-temperature
applications (up to 105°C).
ease of manufacturing, some low-temperature-grade magnet wire has insulation
that can be removed by the heat of soldering. This means that electrical
connections at the ends can be made without stripping off the insulation
