Problems solved by technology

The existing annealed copper conductor structure cannot meet the function of cable movement. When the cable is used in a state of frequent movement, the flexibility of the cable is poor, and it is easy to be broken, pulled off, or the conductor pierces the insulation layer, resulting in a short-circuit fault in the cable.

Embodiment Construction

[0014] The specific embodiments, structures, features, and effects provided in accordance with the present invention will be described in detail below with reference to the drawings and preferred embodiments.

[0015] Such as figure 1 , 2 The shown improvement of a cable copper conductor stranding process includes the following steps:

[0016] (1) Use a stranding machine to bundle and twist multiple round copper monofilaments to the right to form round copper strands;

[0017] (2) Use a stranding machine to divide the multiple round copper strands into multiple layers and twist them to the left to form round copper conductor cores.

[0018] For example: the round copper conductor core is 37×40 / 0.40, that is, the round copper strands are 37 strands, each of which has 40 round copper monofilaments, and the diameter of the round copper monofilament is ∮0.4mm. Improve The comparison between the front conductor stranding process and the improved conductor stranding process is shown in ...

Abstract

The invention relates to an improved stranding process of cable copper conductors. The improved stranding process of the cable copper conductors includes the steps of: (1) utilizing a wire bunching machine to bunch and strand single round copper wires all rightwards to produce round copper strand wires, and (2) utilizing a wire twisting machine to divide the round copper strand wires into layers and restrand the round copper strand wires all leftwards to produce round copper conductor wire cores. According to the improved stranding process of the cable copper conductors, the single round copper wires are all stranded rightwards when in bunching and stranding, and the round copper strand wires are stranded all leftwards when in restranding. Therefore, the flexibility of the conductors is improved, the electrical property and the mechanical property are stable, and the conductor is applicable to the bending, twisting and movable use of the cable.

Description

technical field [0001] The invention belongs to the field of cable manufacturing, and relates to an improvement of a cable copper conductor stranding process. Background technique [0002] In the production of rubber-sheathed flexible cables in the wire and cable industry, the soft copper conductor structure adopts the fifth or sixth soft copper conductor in the national GB / T3956 cable conductor standard of the People's Republic of China. The basic feature of annealed copper conductors is that the single wire diameter of the conductor is relatively thin, so the number of wires is relatively large. When the conductor is produced, the multiple single wires are first bundled into strands, and then the strands are re-twisted together. For a long time, the twisting direction of the conductor is the leftmost layer of the conductor, the twisting direction of the adjacent layer is opposite, and the twisting direction of the strand is opposite to that of the current layer. That is, ...
