Abstract

Aiming at the increasingly stringent requirements for electromagnetic performance and reliability of copper enameled wires in high-frequency applications, a key processing technology system based on conductor pretreatment, multi-layer insulation coating, and automatic control is proposed. Research and analysis show that the purity control of oxygen-free copper rods and the collaborative process of multi-pass drawing and annealing can ensure conductor uniformity; gradient viscosity coating and three-temperature-zone curing effectively improve the integrity of the enamel film. The results indicate that through high-precision molds, closed-loop tension control, catalytic combustion VOCs treatment, combined with SPC process monitoring, the enamel film thickness tolerance of ±2 μm and VOCs removal rate of more than 98% can be achieved. The products meet the requirements of 220℃ heat resistance and high corona resistance, greatly improving the manufacturing level of high-end electromagnetic wires.
