PROCESS FOR THE MANUFACTURE OF ELECTRICAL CONDUCTORS WITH POLYSTERIC RESIN INSULATION, CHARACTERIZED IN SIGNIFICANTLY BY PUT THESE CONDUCTORS THROUGH AN IMPREGNANT BATH CONTAINING A SOLUTION OF POLYESTER RESIN, PRODUCED FROM 1) TETREPHTHALIC ACID OR A DERIVATIVE THEREOF forming esters, alone or in combination with other dicarboxylic acids or derivatives thereof capable of forming esters, and 2) a mixture of dihydroxy compounds and compounds containing more than two hydroxyalkyl groups, the molar ratio between the compounds being with two hydroxyl groups and the having more, between 1: 0.3 and 1: 3, the reaction mixture containing 1.2 to 3 hydroxyl groups for each carboxyl group or its equivalent, with from 5 to 75% of the dihydroxy compounds used diphenols, and the remainder of the dihydroxyl compound being a dialcohol, after which the coated conductors are dried and cured at a temperature of 400 C.
