Electric conductor for use in electric machines

An electric conductor (1) for use in electric machines, comprising

• an electrically conductive conductor core (2) having a substantially rectangular cross-section, wherein the conductor core (2) comprises two longitudinal end faces (6, 7) arranged opposite one another and two transverse end faces (8, 9) arranged opposite one another as well as a total longitudinal extension (3) between a first end (4) and a second end (5) of the conductor core (2),
• at least one insulation layer (10), which insulation layer (10) is arranged around the full circumference of the conductor core (2) at least over a predominant part of the total longitudinal extension (3) of the conductor core (2),
• wherein
• the at least one insulation layer (10) predominantly comprises an extrudable, polymer, thermoplastic material selected from the group of aromatic polysulfones (PAES) or mixtures of aromatic polysulfones (PAES);
• the at least one insulation layer (10) is completely coated with a support layer (16);
• and
• the support layer (16) predominantly comprises an extrudable, polymer, thermoplastic material selected from the group of aromatic polysulfones (PAES) or polyaryletherketone (PAEK) or of mixtures of these materials.
