Process for the manufacture of electrical conductors insulated with polyester resin, characterized in that the bare wires are circulated through an impregnation bath in which a polyester resin obtained by reaction of terephthalic acid or mixtures thereof is dissolved. with other polyvalent carbonic acids, as well as compounds containing hydroxyl, divalent and higher function groups, in which the ratio between the divalent compounds with respect to those of higher function is approximately 1: 0.3 to 1: 3, and each carboxyl group of the corresponding reaction mixture approximately 1.2 to 3 hydroxyl groups, said divalent and hydroxyl group-containing compounds, at least in part, in bis-phenol, the wires thus being coated at a temperature of approximately 400º.
