A method for manufacturing an insulated conductive material includes applying a masking material to one or more regions of a conductive material. Regions of the conductive material other than the masked regions are coated. The regions are coated by electrically charging the conductive material with a first charge polarity, providing a medium of electrically charged insulating material particles that are charged with an opposite polarity, and passing the charged conductive material through the medium, whereby the insulating material particles bind areas of the conductive material and form an insulating film on areas of the surface other than the one or more regions. Afterwards, the insulating film is cured and a solvent is applied to the masking material to thereby remove the masking material. The cured insulated material film is substantially unaffected by the solvent.
