Improvements introduced in the manufacture of electrically insulated conductors, characterized in that they are manufactured by using coating means based on A.) a linear hydroxy polyester of terephthalic acid, optionally mixed with isophthalic acid, and ethylene glycol, with a viscosity index of more than 0.5 B.) a polyester with terminal hydroxyl groups and located in the chain, of terephthalic acid and/or isophthalic acid or derivatives of said acids with a radical located in the group or in the carbonyl groups, which can be easily substituted by the group alkoxy of an alcohol, preferably the lower alkyl esters or the acid chlorides, ethylene glycol and a saturated polyalcohol containing at least 3 hydroxyl groups. and eventually C.) organic solvents.
