The Conductors are drawn and annealed as per the specification. These conductors are insulated with polyester film and polypropylene tape, which have higher insulation resistance even at boiling point of water. Multiple layers of insulation tape are wrapped around the conductor, which ensure high dielectric quality of insulation of the winding wire. The structure of insulation is oriented biaxial, to provide tear resistance and flexibility. The surface of the finished winding wire is reasonably smooth and natural in color.
