Product description:
This product is made of oxygen-free copper rods or electrical round aluminum rods with a certain specification of die extrusion or drawing, and then annealed wires, and then wrap 2-3 layers of polyester film or + electrical non-woven fabric on the copper and aluminum conductors As the winding wire of the insulating layer, the product has good voltage resistance, and the temperature resistance grade is 130℃. It is mainly used for the winding of air-core reactors and other similar electrical equipment. The company uses advanced online eddy current flaw detection equipment to make the product quality more perfect.
