This product is made from oxygen-free copper rods or electrical round aluminum rods, which are extruded or drawn through specific molds and then annealed to form the wire. The wire is then wrapped with 2-3 layers of polyester film or non-woven fabric for electrical use as an insulating layer, resulting in a winding wire. This product offers excellent voltage resistance and a temperature resistance rating of Class B (130°C). It is primarily used for windings in hollow reactors and other similar electrical equipment. Our company employs advanced online eddy current flaw detection equipment to ensure the product quality is more perfect.
