Product Introduction: This product is made from oxygen-free copper rods or electrical round aluminum rods, which are extruded or drawn through molds of specific specifications and then annealed to form conductors. The conductors are 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. The product offers excellent voltage resistance and a temperature resistance rating of Class B (130°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.
