Abstract

The invention belongs to the technical field of electrical equipment, and particularly relates to a processing technique of a high-conductivity duralumin wire. The processing technique comprises the step of controlling elements of an original duralumin rod, the step of controlling the diameter of the original duralumin rod, the step of controlling drawing passes, the step of controlling deformation of each drawing pass and the step of controlling outlet speed of a finished wire. The processing technique can be implemented based on existing production conditions, and needed extra expense and cost are low. In terms of the technique, the duralumin wire can be produced by adopting the technique as long as technological parameters are appropriately changed on an original device, the implementation is technically easy, and the processing technique is convenient to implement and operate. In terms of the effect on the conductivity of the wire, the electric conductivity of the duralumin wire can exceed 62.0%, and the effect is very obvious. According to the processing technique, line losses and energy consumption brought by long-distance electricity transmission can be reduced, economic benefits of power generation enterprises are obviously improved, and the cost of electricity transmission is obviously reduced. Energy can be largely saved, and environmental protection is facilitated.
