Winding wire materials are categorized into lacquer group silk and polyurethane types. Lacquer group silk materials are more common, typically using electrolytic copper wires with a diameter of 0.08mm to 2.00mm as the core wire, which is then coated with multiple layers of insulating lacquer. When selecting winding wire, it is recommended to choose products made from polyurethane material, as polyurethane coated wires offer better heat and corrosion resistance, thereby providing enhanced protection for the core wire and extending the lifespan of the wire.
When selecting enamel-coated wire, appearance is also a factor to consider. The wire should have a smooth and even surface, free of any noticeable dents, waves, scratches, or bubbles. The insulation material should be firmly and evenly coated, with no breaks or shedding.
