Application of copper braided wire of reactor in flat wire welding process
Views:  Addtime:2022-03-14

As we all know, in order to avoid the reduction of effective conductive section caused by skin effect, the welding between copper flat wire and braided wire of reactor with high working frequency adopts ultrasonic welding process, which lays a better technology for the process improvement of reactor production, reduces the overcurrent area and improves the conductivity of reactor

Due to its unique advantages in heat dissipation, welding contact area, fatigue resistance and hardness control, flat copper wire is widely used in wires, leads and mechanical parts of electrical components, vacuum devices, resistors and semiconductor devices. The flat copper wire is a special-shaped structure. When it is used in transformers, reactors and other equipment, it cannot be connected with conventional crimping terminals. It is usually connected by welding. Ultrasonic welding machine is required for welding, and the high temperature near the welding point will cause the insulating paint on the surface of flat copper wire to be damaged or even invalid. Therefore, the paint shall be scraped off before welding to ensure the smooth skin
