A process for providing electrical conductors with a heat resistant, insulating coating of resin. The process comprises passing the conductors through a melt of a resin which is polyester curable through free hydroxy groups, having crosslinking equivalent weight of 400-1600, which is produced by condensation at a temperature corresponding at least to the temperature of the melt to an extent such that no substantial further condensation takes place in the melt.
