Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy cable technology, and in particular to a corrosion-resistant aluminum alloy cable. Background Technology

[0002] Aluminum alloy cables are a new type of power cable made of a series of aluminum alloy materials as conductors, using advanced technologies such as special roll forming and stranding production process and annealing treatment. They are widely used in the internal wiring of residential buildings, commercial buildings, public facilities, etc., including power supply lines, lighting lines and communication lines.

[0003] To this end, the patent specification with publication number CN203573723U discloses an aluminum alloy cable, which includes four insulated cores. The four insulated cores are twisted into a cable and then covered with an outer sheath. The insulated cores include a conductor and a cross-linked polyethylene insulation layer. The conductor is a compressed aluminum alloy conductor. Rubber filler strips are provided in the gaps between the four insulated cores to ensure the roundness of the cable and that the outer diameter of the cable does not exceed the standard, thereby extending the length of the aluminum alloy cable. In addition, the cable also has advantages such as flame retardancy, water resistance, and wear resistance.

[0004] While the aforementioned technologies can retard aluminum alloy cables during use, they are inconvenient for resisting pressure on the cables, making them prone to deformation under pressure. Therefore, a corrosion-resistant aluminum alloy cable is needed to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion-resistant aluminum alloy cable to solve the defect that existing aluminum alloy cables are prone to deformation when subjected to extrusion.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a corrosion-resistant aluminum alloy cable, comprising a cable body and an insulation layer; an insulation layer is installed on the outside of the cable body, a protective sleeve is provided on the outside of the insulation layer, and an auxiliary structure is provided at the middle position of the cable body and the protective sleeve; a reinforcing structure is provided inside the insulation layer, the reinforcing structure including a mounting groove, the mounting groove being opened inside the insulation layer, a support ring being installed inside the mounting groove, and a filling layer being provided inside the mounting groove.

[0007] Preferably, the support ring is made of aluminum alloy and is distributed in a ring inside the mounting groove.

[0008] Preferably, the filler layer is made of insulating adhesive.

[0009] Preferably, the auxiliary structure includes a shielding layer, which is installed on the outside of the insulating layer. A first adhesive layer is installed on the outside of the shielding layer, a moisture-proof layer is provided on the outside of the first adhesive layer, and a third adhesive layer is provided on the outside of the moisture-proof layer.

[0010] Preferably, the material of the shielding layer is an aluminum-plastic composite strip.

[0011] Preferably, the moisture-proof layer is made of water-blocking tape.

[0012] Preferably, the protective sleeve is made of polyethylene.

[0013] Compared with the prior art, the beneficial effect of this utility model is that the cable body can be strengthened by setting up a reinforced structure;

[0014] By incorporating a reinforcing structure, the use of a support ring during cable installation can enhance the strength of the insulation layer, preventing deformation under pressure. Furthermore, the filler layer possesses a certain degree of adhesion and flexibility, allowing it to fill gaps in the installation groove, fix the position of the support ring, and prevent it from shifting or swaying during cable operation, thus completing the reinforcement work.

[0015] By incorporating auxiliary structures, the use of a shielding layer on the cable body can effectively prevent external electromagnetic interference, while also providing some moisture and corrosion protection. Furthermore, the moisture-proof layer can absorb moisture from inside the cable, preventing moisture buildup and thus avoiding corrosion of the aluminum alloy conductor. This achieves the effects of anti-interference, moisture protection, and corrosion prevention. Attached Figure Description
