1. As the ribbon copper foil spiral winding in the center fiber, the center fiber plays a role in bearing the longitudinal tension; and due to the winding of the copper foil to retain a certain gap between the wire body in the bending of the ribbon copper foil can be avoided to avoid a large deformation of the force, so that the copper foil wire has a very good elasticity, softness and resistance to bending performance, especially bending resistance is much higher than the ordinary round wire conductor.If you choose copper alloy foil wire, its bending resistance will be greater than the copper foil wire.

2. Due to the spiral winding of the winding assembly, the single wire diameter increases, the resistance value per meter increases, the use of the product needs to be based on the temperature resistance level of the fiber, the above factors make the selection of copper foil wire to a certain degree of restriction.

3. By using a copper alloy as a conductor, the bending resistance of the copper foil wire can be further increased, but the resistance value per meter will further increase.

4. By increasing the surface treatment process of copper foil wire, the antioxidant performance of the product can be significantly improved to meet the requirements of high-end customers for salt spray test of the product.
