Energy-saving and consumption-reducing cable conductor and production method thereof

Abstract

The invention relates to the technical field of power cables, in particular to an energy-saving and consumption-reducing cable conductor and a production method thereof. The cable conductor comprises a multi-layer conductor structure, and the multi-layer conductor structure is formed by twisting a plurality of wires; the wires are required molded lines drawn at a time through a plurality of molds, the structures between single wires of the cable conductor are tighter, and the filling coefficient between the wires reaches 0.97, so the outer diameter of the conductors is reduced, the outer diameter of the finished cable is averagely reduced by more than 5%, and materials such as insulation and sheaths are effectively saved; meanwhile, the wires which are matched with one another and are of a multi-layer conductor structure are mutually twisted and are properly shaped together, and the deformation stretching is not required to be performed by pressing and drawing; the power consumption of the stranding machine can be reduced under a relatively small traction force, so an energy-saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to an energy-saving and consumption-reducing cable conductor and a production method thereof. Background technique [0002] Cables have many nominal cross-sections of different specifications to meet different use requirements. Small-section cables can use a single solid core conductor. As the cross-sectional area of ​​the conductor increases, its bending performance decreases, and even the processing, manufacturing and installation of the cable cannot be performed. Laying, and the single wire as the conductor of the cable is also easily affected by material inhomogeneity or quality defects in the manufacturing process, which reduces the reliability and mechanical strength of a single wire. The quality defects and mechanical strength of the stranded wire are dispersed, and will not be concentrated on a certain point of the conductor. The conductor stranded has the characteristi...

AI Technical Summary

Problems solved by technology

In the prior art, there are gaps between the stranded wire cores. In order to save the cable filling and materials of each layer and reduce the cost, the stranded wires are pressed and pulled layer by layer in the existing cable processing process. This kind of cable There are shortcomings in the conductor process. After the conductor is pressed and drawn, the cross section of the conductor is deformed or stretched longitudinally, and the resistance of the conductor increases due to lattice deformation.
