At least one outer core layer is stranded outside the inner core, and the outer core layer is stranded and spliced along the outer circumference of the inner core by a plurality of aluminum alloy profile wires with a trapezoidal cross-section. An outer protective layer is coated outside the outer core layer, and an outer phase transition layer is arranged between the outer core layer and the outer protective layer. The outer phase transition layer includes a porous fiber material and a phase transition material coated on the surface of the porous fiber material. In the aluminum alloy stranded wire of the utility model, after adding the phase transition material, when the external temperature changes, the phase transition material absorbs and releases heat, so that the temperature of the stranded wire is maintained near the phase transition temperature of the phase transition material, and does not change greatly with the ambient temperature, delaying the aging speed of the stranded wire. In rainy and snowy weather, ice can be prevented from forming on the stranded wire, reducing the load on the stranded wire and prolonging the service life of the stranded wire;

A tensile mechanism is arranged outside the second aluminum alloy profile wire, and an outer protective layer is adhered outside the tensile mechanism. A wear-resistant mechanism is arranged outside the outer protective layer.

[0008] When using a wear-resistant enhanced aluminum alloy stranded wire with this technical solution, during use, a wear-resistant mechanism is provided to improve its wear resistance and thus its practicality.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0026] Please refer to Figures 1 - 5 , an embodiment provided by the present invention: a wear-resistant and enhanced aluminum alloy stranded wire, including a wire core 1 and a filling layer 2. The filling layer 2 is evenly filled outside the wire core 1. The outside of the wire core 1 is stranded with a first aluminum alloy profile wire 3, and the outside of the first aluminum alloy profile wire 3 is stranded with a second aluminum alloy profile wire 4. A tensile mechanism 5 is arranged outside the second aluminum alloy profile wire 4;

[0027] The tensile mechanism 5 includes a tensile layer 501, and the tensile layer 501 is arranged between the second aluminum alloy wire 4 and the outer protective layer 6. Cavities 503 are evenly arranged inside the tensile layer 501, and tensile cores 502 are arranged inside the cavities 503;

[0028] The cross-section of the tensile core 502 is circular. The material of the tensile core 502 is polyethylene, and the outer edge of the tensile core 502 fits with the inner wall of the cavity 503;

[0029] There are multiple cavities 503. The cross-sections of the multiple cavities 503 are all circular, and the multiple cavities 503 are distributed in a ring shape;

[0030] Specifically, as Figure 1 、 Figure 3 、 Figure 4 shown, during use, by arranging the tensile cores 502, the toughness during use is improved, thereby improving its practicality and avoiding the phenomenon of being pulled and broken during use;

[0031] And an outer protective layer 6 is adhered to the outside of the tensile mechanism 5, and a wear-resistant mechanism 7 is arranged on the outside of the outer protective layer 6;

[0032] The wear-resistant mechanism 7 includes a strengthening layer 703, and the strengthening layer 703 is arranged on the outside of the outer protective layer 6. A wear-resistant layer 702 is adhered to the outside of the strengthening layer 703, and wear-resistant protrusions 701 are evenly arranged on the outside of the wear-resistant layer 702;

[0033] There are multiple wear-resistant protrusions 701. The multiple wear-resistant protrusions 701 are distributed in a ring shape, and the materials of the multiple wear-resistant protrusions 701 are all polyester fiber materials;

[0034] The cross-section of the wear-resistant layer 702 is annular, and the material of the wear-resistant layer 702 is Kevlar fiber;

[0035] Specifically, as Figure 1 、 Figure 2 、 Figure 5 shown, during use, by arranging the strengthening layer 703, the wear-resistant performance of the outer protective layer 6 can be improved under the action of the wear-resistant layer 702 and the wear-resistant protrusions 701, thereby improving its practicality and then increasing its service life.

[0036] Working principle: When this utility model is in use, first of all, a strengthening layer 703 is sprayed on the outer side of the outer protective layer 6. The material of the strengthening layer 703 is Teflon coating. This material has good moisture resistance and abrasion resistance, and the usage cost is not high. Therefore, spraying the strengthening layer 703 on the outer side of the outer protective layer 6 can not only improve the abrasion resistance and moisture resistance of the outer protective layer 6, but also reduce the cost during use. At the same time, a wear-resistant layer 702 is arranged on the outer side of the strengthening layer 703. The material of the wear-resistant layer 702 is a Kevlar fiber layer, which can further improve the abrasion resistance of the outer protective layer 6. And with the cooperation of the wear-resistant ridges 701, the abrasion resistance of the outer protective layer 6 can be further improved, thus avoiding the phenomenon of damage to the outer protective layer 6 during transportation or erection, and improving its practicability.

[0037] Then, by providing a tensile layer 501, the tensile performance of the wire core 1 during use can be initially improved, avoiding the phenomenon of being pulled apart during erection. At the same time, by providing a tensile core 502, the material of the tensile core 502 is polyester fiber. Since the binding force between the molecular chains of polyester fiber is relatively large, and the interaction force between adjacent molecular chains is enhanced, this densely arranged molecular structure enables the tensile core 502 to have the properties of high strength and high toughness, and then further improves the tensile performance of the wire core 1 to increase the service life of the wire core 1 during use.
