Technical Field
[0001] This utility model relates to the field of aluminum alloy cable technology, specifically an aluminum alloy cable. Background Technology
[0002] With the continuous development of the power transmission industry, aluminum alloy cables have been widely used in many fields due to their advantages such as low cost, light weight, and good conductivity. However, existing aluminum alloy cables still have some shortcomings.
[0003] For example, in some complex environments, cables have poor bending resistance and are prone to damage to internal conductors due to bending, affecting power transmission. At the same time, the fire resistance and moisture resistance of cables need to be improved. When used in high-temperature and humid environments, there are safety hazards, which reduces the service life and reliability of the cables.
[0004] Therefore, this utility model provides an aluminum alloy cable to solve the above problems. Utility Model Content

[0014] Beneficial effects
[0015] This utility model provides an aluminum alloy cable. Compared with the prior art, it has the following advantages:
[0016] 1. This aluminum alloy cable uses high-purity aluminum alloy material for its core, which is regularly concentrically stranded and supplemented with an anti-oxidation layer. This effectively reduces resistance, enhances flexibility and mechanical strength, and ensures stable conductivity. The copper wire mesh shielding layer can isolate external electromagnetic interference, so that the cable can still ensure stable internal signal transmission in complex electromagnetic environments, meeting the usage requirements of high electromagnetic environment scenarios.
[0017] 2. This aluminum alloy cable has a multi-layered protection system consisting of an insulation layer, an anti-bending layer, a fireproof and moisture-proof layer, a buffer protection layer, and a wear-resistant and corrosion-resistant sheath layer. It protects the internal structure of the cable from multiple dimensions, including insulation, anti-bending, fireproof and moisture-proof, impact resistance and wear resistance. At the same time, the anti-bending layer ensures the safety of the cable when it is bent, and the anti-slip texture of the sheath layer facilitates installation and laying, significantly improving the practicality and ease of use of the cable.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] Reference Figures 1 to 2 This application provides an aluminum alloy cable, including a cable core 1, a cable sheath 2 on the outside of the cable core 1, an insulation layer 21, an anti-bending layer 22 fixedly installed on the outside of the insulation layer 21, a fireproof and moisture-proof layer 23 fixedly installed on the outside of the anti-bending layer 22, a shielding layer 24 fixedly installed on the outside of the fireproof and moisture-proof layer 23, a buffer protection layer 25 fixedly installed on the outside of the shielding layer 24, and a sheath layer 26 fixedly installed on the outside of the buffer protection layer 25.
[0025] In an optional embodiment: the cable core 1 is made of high-purity aluminum alloy material, and the cable core 1 is formed by stranding aluminum alloy single wires.
[0026] It should be noted that the stranding method is a regular concentric stranding, and the stranding directions of adjacent layers are opposite. This structure can effectively improve the conductor's flexibility and mechanical strength, reduce resistance, and improve conductivity. At the same time, a thin anti-oxidation layer, such as a tin plating layer, is plated on the conductor surface to prevent oxidation during use, further ensuring the stability of the cable's conductivity.
[0027] In an optional embodiment, the insulating layer 21 is made of cross-linked polyethylene material.
[0028] It should be noted that this material has good insulation and heat resistance properties. The thickness of the insulation layer 21 is precisely designed according to the rated voltage of the cable to ensure that the conductor can be effectively isolated from the outside world under normal operating voltage, preventing leakage.
[0029] In an optional embodiment, the anti-bending layer 22 consists of a plurality of spirally wound elastic support strips made of a rubber material with high elasticity and flexibility.
[0030] It should be noted that when the cable is subjected to bending force, the elastic support strip can provide elastic support, limiting excessive deformation of the insulation layer 22 and the conductor, thereby protecting the internal structure from damage and improving the cable's bending resistance.
[0031] In an optional embodiment: the fireproof and moisture-proof layer 23 consists of two layers, an inner layer of fireproof mica tape and an outer layer of moisture-proof polymer film.
[0032] It should be noted that mica tape has excellent high-temperature resistance and can form a dense heat insulation layer in high-temperature environments, preventing the spread of flames and providing fire protection. The moisture-proof polymer film has excellent waterproof and breathable properties, preventing external moisture from penetrating the cable while allowing internal moisture to escape, ensuring normal cable operation in humid environments.
[0033] In an optional embodiment, the shielding layer 24 is made of woven copper wire mesh.
[0034] It should be noted that copper wire mesh has excellent electromagnetic shielding performance, which can effectively shield external electromagnetic interference and ensure the stability of signal transmission inside the cable. It is suitable for occasions with high requirements for the electromagnetic environment.
[0035] In an optional embodiment, the buffer protective layer 25 is made of a buffer foam material, with multiple micro airbags evenly distributed inside.
[0036] It should be noted that when the cable is subjected to external impact, the cushioning foam material and micro airbags can absorb and disperse the impact force, reduce the impact of external force on the internal structure, and play a good protective role.
[0037] In an optional embodiment: the sheath layer 26 is made of polyvinyl chloride material, and the surface of the sheath layer 26 is provided with anti-slip texture.
[0038] It should be noted that vinyl chloride material has properties such as wear resistance, aging resistance, and corrosion resistance. The anti-slip texture on the surface of the sheath layer 26 facilitates the installation and laying of cables.
[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0040] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
