Description

Technical Field

[0001] This utility model belongs to the field of cable technology, and in particular relates to a rare earth high-speed rail aluminum alloy cable. Background Technology

[0002] Cables are materials used for power, communication, and related transmission applications. With societal development, the application scope and occasions of cables are expanding, and the requirements for cables are becoming increasingly stringent. Currently, due to copper's excellent electrical properties, domestic cables generally use copper as the conductor. However, copper is much more expensive than aluminum. Many researchers have been developing aluminum alternatives to copper to optimize resource utilization. However, ordinary aluminum core cables have poor mechanical and corrosion resistance. Rare-earth high-speed iron aluminum alloy conductors, on the other hand, possess creep resistance, high flexibility, strong ductility, and low rebound characteristics. Under the same current carrying capacity, the weight of a rare-earth high-speed iron aluminum alloy conductor is about half that of a copper conductor, and its price is about one-third that of copper. With the increasing demand for cables in my country, using rare-earth high-speed iron aluminum alloy conductor cables to replace copper conductor cables has the benefits of reducing material costs, optimizing resource utilization, and meeting the needs of my country's power construction.

[0003] In applications such as power line inspection and surveying using drones, rare earth high-speed rail aluminum alloy cables can demonstrate the advantages of reducing cable weight while ensuring stable power transmission. However, most rare earth high-speed rail aluminum alloy cables on the market currently have poor puncture resistance. During use, if they are struck by sharp objects, they can easily puncture the cable core, leading to cable damage and certain usage risks. Utility Model Content

[0005] To solve the above problems, this utility model is implemented as follows: a rare earth high-speed rail aluminum alloy cable includes: multiple cable cores, each of the multiple cable cores being composed of a rare earth high-speed rail aluminum alloy conductor and a first insulation layer, the multiple first insulation layers being located outside the multiple rare earth high-speed rail aluminum alloy conductors; a filling layer disposed on the outer wall of the cable cores, the filling layer being provided with an anti-puncture mechanism for protecting the cable cores; and a second insulation layer disposed outside the anti-puncture mechanism.

[0006] Preferably, the anti-puncture mechanism includes: a plurality of steel rings fixedly installed on the outer wall of the filling layer, and a wire mesh is provided between the plurality of steel rings.

[0007] Preferably, the outer wall of the second insulating layer is provided with a flame-retardant layer, which is made of ceramicized silicone rubber material.

[0011] Preferably, the outer wall of the wear-resistant layer is provided with a plurality of anti-slip strips, and the second insulating layer and the plurality of first insulating layers are both made of rubber.

[0012] Compared with related technologies, the rare earth high-speed rail aluminum alloy cable provided by this utility model has the following beneficial effects:

[0013] Compared with existing technologies, the rare earth high-speed rail aluminum alloy cable provided by this solution can fix the position of multiple cable cores through the use of a filler layer. The anti-puncture mechanism composed of multiple steel rings and multiple steel wire mesh can protect the multiple cable cores composed of rare earth high-speed rail aluminum alloy conductors and the first insulation layer.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a rare earth high-speed rail aluminum alloy cable, such as Figure 1-3 As shown, the rare earth high-speed rail aluminum alloy cable includes: multiple cable cores 1, each of the multiple cable cores 1 being composed of rare earth high-speed rail aluminum alloy conductors 2 and a first insulation layer 3, the multiple first insulation layers 3 being located outside the multiple rare earth high-speed rail aluminum alloy conductors 2 respectively; a filling layer 4 disposed on the outer wall of the cable core 1, the filling layer 4 being provided with an anti-puncture mechanism 5 for protecting the cable core 1; and a second insulation layer 6 disposed outside the anti-puncture mechanism 5.

[0021] In this embodiment, the rare earth high-speed rail aluminum alloy cable comprises multiple cable cores 1, each cable core 1 consisting of a rare earth high-speed rail aluminum alloy conductor 2 and a first insulation layer 3 wrapped around it. The first insulation layer 3 provides initial insulation protection for the rare earth high-speed rail aluminum alloy conductor 2. Multiple cable cores 1 are combined together, and a filling layer 4 is provided on the outer wall of the cable core 1. The filling layer 4 serves to fill and fix the position of the cable core 1, and also has a puncture-resistant mechanism 5 on it to protect the cable core 1. When the cable is hit by a sharp object, the puncture-resistant mechanism 5 can block the sharp object and prevent it from directly puncturing the cable core 1, protecting the cable core 1 from damage, thereby reducing the risk of cable damage and safety hazards. A second insulation layer 6 is provided outside the puncture-resistant mechanism 5, which further insulates and protects the entire cable, ensuring the safety and stability of the cable during power transmission. Through the synergistic effect of each part of the structure, the rare earth high-speed rail aluminum alloy cable has advantages such as light weight and low cost, and also improves the overall puncture resistance and insulation performance of the cable.

[0022] In a further preferred embodiment of the present invention, the anti-puncture mechanism 5 includes: a plurality of steel rings 9 fixedly installed on the outer wall of the filling layer 4, and a wire mesh 10 is provided between the plurality of steel rings 9.

[0023] In this embodiment, the anti-puncture mechanism is used to protect the cable core 1. When the cable is struck by a sharp object, the steel ring 9 and the wire mesh 10 can effectively prevent the sharp object from penetrating directly into the cable. The wire mesh 10 is made of many interwoven steel wires and has high toughness and strength. When a sharp object comes into contact with the wire mesh 10, the wire mesh 10 can disperse the force of the sharp object through its dense mesh structure and use the strength of the steel wires to wrap around and jam the sharp object, preventing the sharp object from continuing to penetrate. This effectively protects the cable core 1 from being punctured, reduces the risk of cable damage, and ensures the safety and stability of the cable during use. Under the action of the steel ring 9, it can not only block sharp objects but also improve the compressive strength of the cable.

[0024] In a further preferred embodiment of the present invention, a flame-retardant layer 7 is provided on the outer wall of the second insulating layer 6, and the flame-retardant layer 7 is made of ceramicized silicone rubber material.

[0025] In this embodiment, a flame-retardant layer 7 made of ceramicized silicone rubber material is provided on the outer wall of the second insulation layer 6. When the cable is in a high-temperature scenario such as a fire, the ceramicized silicone rubber material will undergo a ceramicization reaction when heated, and its physical state will gradually change from the original rubber state to a hard ceramic state. This ceramic material has excellent thermal stability and low thermal conductivity, which can effectively block the conduction of high-temperature heat from the outside to the inside of the cable, reduce the rate of temperature rise inside the cable, provide thermal protection for the cable core 1, and prevent it from being damaged by high temperature. In addition, the ceramicized flame-retardant layer 7 has a compact structure, which can isolate air and inhibit the spread of flames on the surface of the cable, playing an excellent flame-retardant role, reducing the damage of fire to the cable, and ensuring the safety and stability of the cable in a high-temperature environment.

[0026] In a further preferred embodiment of the present invention, the outer wall of the flame retardant layer 7 is provided with a wear-resistant layer 8, which is made of PMMA film material.

[0027] In this embodiment, a wear-resistant layer 8 made of PMMA film material is provided on the outer wall of the flame-retardant layer 7. It has high hardness and wear resistance, which can effectively resist the friction and scratching of external objects on the cable surface, reduce the wear of the cable outer wall, and avoid damage to the cable outer wall due to long-term friction. This also prevents external moisture, impurities, etc. from entering the cable and damaging the internal conductor and insulation layer. At the same time, PMMA film material also has good weather resistance and chemical stability, and can maintain its wear resistance under different environmental conditions, providing long-term effective protection for the cable, extending the cable's service life, and ensuring that the cable can operate stably and reliably under various complex working conditions.

[0028] In a further preferred embodiment of the present invention, a common support bar 11 is fixedly installed on a plurality of cable cores 1, and the support bar 11 is made of rubber material.

[0029] In this embodiment, a support strip 11 made of rubber material is fixedly installed on multiple cable cores 1. The rubber material has good flexibility and elasticity. The support strip 11 can support and fix multiple cable cores 1, so that the cable cores 1 maintain a relatively stable positional relationship, thereby ensuring the regularity of the internal structure of the cable.

[0030] In a further preferred embodiment of the present invention, the filling layer 4 is made of water-resistant yarn material, and the wire mesh 10 is made of alloy steel wire material.

[0031] In this embodiment, the filling layer 4 is made of water-blocking yarn material. When the cable is in a humid environment or when moisture enters, the water-blocking yarn material can quickly absorb and lock in the moisture with its own characteristics, preventing the moisture from further spreading and penetrating inside the cable, avoiding damage to the cable core 1, and ensuring the electrical and insulation performance of the cable. The wire mesh 10 is made of alloy steel wire material. Alloy steel wire has high strength and toughness. When the cable is hit by a sharp object, the wire mesh 10 formed by the alloy steel wire can use its high strength to block the sharp object from penetrating, and at the same time use its toughness to disperse the force of the sharp object, effectively protecting the cable core 1 from being punctured, reducing the risk of cable damage, and ensuring the safety and stability of the cable during use.

[0032] In a further preferred embodiment of the present invention, the outer wall of the wear-resistant layer 8 is provided with a plurality of anti-slip strips, and the second insulating layer 6 and the plurality of first insulating layers 3 are both made of rubber.

[0033] In this embodiment, the use of multiple anti-slip strips can increase the friction of the outer surface of the cable, so that the cable can be stably laid in the installation position and is not easily displaced. Through the second insulation layer 6 of rubber material and multiple first insulation layers 3, the cable has good insulation performance, which can reliably isolate the rare earth high-speed iron aluminum alloy conductor 2 from the external environment, prevent current leakage, and ensure the safety and stability of power transmission.

[0034] In summary, compared with related technologies, this solution, through the use of the filling layer 4, can fix the position of multiple cable cores 1. The anti-puncture mechanism 5, composed of multiple steel rings 9 and multiple wire meshes 10, can protect the multiple cable cores 1 composed of rare earth high-speed rail aluminum alloy conductors 2 and the first insulation layer 3. When the cable is hit by a sharp object, the anti-puncture mechanism 5 can block the sharp object and prevent it from directly puncturing the cable cores 1, thus protecting the cable cores 1 from damage. This solves the problems of insufficient puncture resistance, easy damage to the cable cores due to sharp object collisions, and the risk of use in existing rare earth high-speed rail aluminum alloy cables.
