ABSTRACT
This article deals exclusively with enameled wire, namely, copper or aluminum wire coated with a very thin layer of insulation. The first section is devoted to the presentation of enamel insulated wire currently available on the market. Impregnating varnish will be discussed but the varnishes themselves will not be mentioned. The word enamel, originally reserved for the description of vitrified crystalline materials, is used here by extension in the designation of irregularly structured insulation products, created in thin layers at a high temperature. Another section is devoted to the chemistry of these enamels and to development techniques.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

INTRODUCTION
This presentation deals exclusively with enamelled wires, i.e. insulating enamels applied to copper (or aluminium) conductors.
The meaning of the word enamel, originally reserved for the designation of vitrified crystalline materials, is used here, by extension, to designate insulating products of less regular structure, built up in thin layers, at high temperature, on the conductor to be covered.

Standards and norms
Most of the French standards listed are the result of work carried out by the corresponding IEC commissions. They consist of a copy of the French version of the international standard. As these documents are constantly evolving, it is advisable to check the standards catalogs to ensure that new updates have not been published at the time of consultation.
