The Introduction of Non-Woven Polyester Film Coated Wire

Non-woven polyester film coated copper (aluminum) wire is a wire made of oxygen-free copper rod or electrical round aluminum rod that has been extruded or drawn and annealed by a die of the required specifications, and then wrapped with 2-3 layers of polyester film or electrical non-woven fabric as an insulating layer on the aluminum-copper conductor. Non-woven polyester film coated wire has good voltage resistance and a temperature resistance grade is B grade 130℃ or F grade 155℃. It is mainly used for windings of reactors, dry-type transformers and other electrical equipment.
