Embodiment

[0024] The method for manufacturing a circular compacted aluminum alloy conductor of the present invention uses a circular single wire for compaction in a coaxial twisting manner, and the manufacturing method is specifically as follows:

[0025] 1) After the circular single wire is wound in the middle conductor in the same direction, it is pressed by the pressing die;

[0026] 2) Coat the outside of the compressed conductor with an insulating layer;

[0027] 3) Put a PVC jacket on the outer layer of the insulating layer.

[0028] The traditional twisting direction is left-right-left, and the same-direction twisting method of the present invention is the left-left-left twisting method.

[0029] Due to the co-directional stranding, each layer will become tighter and tighter during the stranding process, so when this method is adopted, the pitch diameter ratio of each layer is 1-2 larger than that of the traditional stranding;

[0030] When traditionally stranded aluminum alloy...

Abstract

The invention relates to a fabrication method for round pressing of an aluminum-alloy conductor. A round single wire is pressed by a single-way twisting mode. The fabrication method comprises the following steps of 1) winding the round single wire after an intermediate conductor by the single-way twisting mode, and pressing the conductor by a press die; 2) coating the external part of the pressed conductor with an insulation layer; and 3) sleeving the outer layer of the insulation layer with a PVC jacket. Compared with the prior art, the fabrication method has the advantages of low processing cost, material saving, high pressing coefficient and the like, and is convenient to fabricate.

Description

technical field [0001] The invention relates to a method for manufacturing a conductor, in particular to a method for manufacturing a circular compacted aluminum alloy conductor. Background technique [0002] 8000 series aluminum alloy is a new type of conductor material. Compared with ordinary aluminum conductors, its bending performance, creep resistance and corrosion resistance are greatly improved, which can ensure the continuous performance of the cable under long-term overload and overheating. 8000 series aluminum alloy conductors can greatly improve the conductivity and high temperature resistance of aluminum alloy cables, and at the same time solve the problems of electrochemical corrosion and creep of pure aluminum conductors. The conductivity of aluminum alloy is 61.8% of the most commonly used benchmark material copper IACS, and the current carrying capacity is 79% of copper, which is better than pure aluminum standard [0003] At present, there are two main type...
