Abstract: An electric wire comprises a non-oxidized conductor of copper alloy having no outer coating and in direct contact with a PTFE-based sheath. It is fabricated as follows: providing a copper alloy conductor without an outer coating; forming a sheath of a PTFE-based material around the conductor; and heating the wire in order to evaporate the lubricant and sinter the sheath. In order to avoid oxidizing the copper during the heating step, the wire is heated mainly in an atmosphere having a low oxygen content. The lubricant evaporation and/or sintering line for stabilizing the sheath of the electric wire comprises one or more ovens, each having an enclosure in which an atmosphere having a low oxygen content is maintained.
