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 polyimide film or non-woven fabric for electrical use as an insulating layer, resulting in a winding wire. The product exhibits excellent voltage resistance and has a temperature rating of Class E (180°C). It is primarily used for windings in transformers, hollow reactors, and other similar electrical equipment. Our company employs advanced online eddy current flaw detection equipment to ensure the product quality is further perfected.
