Polyimide film copper (aluminum) wire
Product description:
This product is made of oxygen-free copper rods or electrical round aluminum rods that are annealed after being extruded or drawn by a certain specification die, and then wrapped 2-3 layers of polyester imide film or + electrical materials on the copper and aluminum conductors. The winding wire with woven fabric as the insulating layer has good voltage resistance, and the temperature resistance level is 180℃. It is mainly used for winding of transformers, 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.
Executive standard:GB/T7673-2008 and corporate standards
