Aluminum alloy photovoltaic cable stranding device and stranding method

Abstract

The invention mainly relates to the technical field of cable processing, and provides an aluminum alloy photovoltaic cable stranding device and a stranding method. The aluminum alloy photovoltaic cable stranding device comprises a wire spool and a wire stranding disc and further comprises a plurality of rotary disc assemblies, and the wire spool is driven by the rotary disc assemblies to rotate in the vertical axial direction; and the wire stranding disc is driven by a first rotary driving device to rotate. According to the invention, the cost is low, the cost of a single rotating disc assembly is controllable, the rotating disc assembly is started as required during use, and energy consumption can be greatly saved for stranding when a small number of single wires are required; a single wire is led out in the horizontal direction, no torsion internal stress exists, the stranded wire structure is stable, especially for a circular insulated wire core, the wire core does not have rebound stress, and the cabling roundness and the cabling diameter accuracy can be guaranteed; the wire spool rotates axially, the safety coefficient is high, the wire spool can be directly loaded into the rotating disc assembly through the top truss, and secondary loading of an additional feeding device is not needed.

Description

technical field [0001] The invention mainly relates to the technical field of cable processing, in particular to a twisting device and a twisting method of an aluminum alloy photovoltaic cable. Background technique [0002] Aluminum alloy power cable is a new type of power cable with AA8030 series aluminum alloy material as conductor, using special roll forming wire stranding production process and advanced technology such as annealing treatment, alloy power cable makes up for the shortcomings of previous pure aluminum cables, although The electrical conductivity of the cable is not improved, but the bending performance, creep resistance and corrosion resistance are greatly improved, which can ensure the continuous performance of the cable when overloaded and overheated for a long time. The use of AA-8030 series aluminum alloy conductors can It greatly improves the conductivity and high temperature resistance of aluminum alloy cables, and solves the problems of pure aluminum...

Problems solved by technology

[0004] The first problem is that the cost is high and the adaptability is poor. The cost of a frame-type stranding machine generally needs 200,000-250,000, and the number of cable winding reels equipped with the frame-type stranding machine is certain, such as a 4*5 frame-type stranding machine. The wire machine can be equipped with 20 winding reels. When the manufacturer’s cable stranding requires more than 20 single wires, the above-mentioned 4*5 frame type wire twisting machine is not enough, and a higher specification frame type wire stranding machine needs to be purchased and then Increase the cost, and when the required single wires do not exceed 20, it is also necessary to open the entire 4*5 frame-type twisting machine and related machines, which increases the cost of power consumption;

[0005] The second problem is that in the process of unwinding, as time goes by, the amount of remaining wire on the cable becomes less and less, and the thickness on the winding reel decreases, which leads to changes in the threading distance and distance, especially for frame-type stranding machines. When the reels are placed side by side, contact and friction between single wires are easy to occur during the unwinding process, and the wire tension is also constantly changing, which is prone to greater wear and tear when passing through the twisting reel, which will affect the quality of the subsequent twisted cable;
