Electrical Flat Copper Wire and Flat Aluminum Wire
The Electrical Flat Copper Wire is a conductor extruded or drawn from the oxygen-free copper rod through certain molding. The Electrical Flat Copper Wire can be taken as the finished product for use, and can also be an in-progress product, which is widely applied for windings of the motors, transformers, reactors and other similar electrical equipment.
The Electrical Flat Aluminum Wire is a conductor formed through continuous extrusion from the oil-free electrical round aluminum rod through certain molding, and is widely applied for the windings of the motors, transformers, electric welding machines and other similar electrical equipment.
The Tensile Strength and Elongation of the Flat Copper Wire shall conform to the provisions in the following table:
