Abstract
Description
Technical Field
[0001] This utility model relates to electromagnetic wire technology, specifically a high wear-resistant glass fiber-coated iron-chromium round wire for trams. Background Technology
[0002] Trams, also known as trams or light rail, are light urban rail transit systems that are powered by electricity and run on tracks. Trains generally have no more than five cars. Trams are powered by electricity and do not emit exhaust fumes, making them a pollution-free and environmentally friendly mode of transportation.
[0003] Existing tram power cables generally use copper cores as the base material and halogen-free flame-retardant polyethylene as the outer sheath material, with a maximum heat resistance temperature of 90℃. However, during long-term operation or under special conditions, the operating temperature will be much higher than this heat resistance temperature, causing the outer sheath to age rapidly due to excessive temperature, resulting in a significant reduction in performance and failure to meet operational requirements. In addition, the track cable needs to withstand frequent compression, pulling, and friction. The outer sheath material has poor strength and is easily damaged, and the strength of the copper base material cannot withstand long-term compression, pulling, and friction. Therefore, the cable needs to be replaced frequently. Utility Model Content
[0004] To overcome the shortcomings of the prior art, this utility model provides a high wear-resistant glass fiber coated iron-chromium round wire for trams, which can withstand high temperatures, and has high strength, good elasticity and high wear resistance.
[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: Figure 1 As shown, a high wear-resistant glass fiber-coated iron-chromium round wire for trams includes a substrate and an insulation layer. The insulation layer is wrapped around the outer periphery of the substrate. The substrate is an iron-chromium-aluminum substrate. The insulation layer includes a connecting layer and a wear-resistant layer. The wear-resistant layer is connected to the substrate through the connecting layer and is a glass fiber cloth layer.
[0006] Preferably, a protective layer is provided on the outer periphery of the wear-resistant layer.
[0007] Preferably, both the connecting layer and the protective layer are paint layers.
[0008] Preferably, the paint layer is a high-temperature insulating paint layer.
[0009] Preferably, the thickness of the connecting layer is 0.1-0.5 mm.
[0010] Preferably, the thickness of the protective layer is 0.1-0.5 mm.
[0011] Preferably, the thickness of the wear-resistant layer is 1-5 mm.
[0012] In summary, this utility model achieves the following technical effects:
[0013] This utility model discloses a high wear-resistant glass fiber-coated iron-chromium round wire for trams. It uses iron-chromium-aluminum wire as the base material, which has high strength and good elasticity. It can withstand frequent compression, pulling and friction without deformation. Moreover, it uses a glass fiber cloth layer as a wear-resistant layer, combined with a connecting layer and a protective layer, so that the insulation layer not only has an insulation function, but also has high temperature resistance and wear resistance, is not easy to break, and has a long service life.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0022] Example 1:
[0023] like Figure 1 As shown, a high wear-resistant glass fiber coated iron-chromium round wire for trams includes a substrate and an insulation layer. The insulation layer is wrapped around the outer periphery of the substrate. The substrate is an iron-chromium-aluminum substrate 1. The insulation layer includes a connecting layer 2 and a wear-resistant layer. The wear-resistant layer is connected to the substrate through the connecting layer 2. The wear-resistant layer is a glass fiber cloth layer 3.
[0024] Among them, the iron-chromium-aluminum alloy wire is lighter than copper wire, and its yield strength and tensile strength are higher than those of copper wire, resulting in good overall strength and elasticity of the substrate, meeting the requirement of not deforming even after long-term frequent compression, pulling and friction. Glass fiber is a high-performance inorganic non-metallic material with many varieties. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. Glass fiber cloth is woven from glass fiber, which significantly improves wear resistance. Combined with the paint layer used for the connecting layer 2 and the wear-resistant layer, the coefficient of friction is reduced, thereby reducing the extrusion friction between the wear-resistant layer and the substrate or external structure, further improving the wear resistance of the entire iron-chromium round wire. Moreover, the connecting layer 2 and the protective layer 4 are both coated with high-temperature insulating paint. Combined with the high-temperature resistance of iron-chromium-aluminum and glass fiber, the entire iron-chromium round wire can withstand high temperatures.
[0025] This utility model discloses a high wear-resistant glass fiber-coated iron-chromium round wire for trams. It uses iron-chromium-aluminum wire as the base material, which has high strength and good elasticity. It can withstand frequent compression, pulling and friction without deformation. Moreover, it uses a glass fiber cloth layer 3 as a wear-resistant layer, combined with a connecting layer 2 and a protective layer 4, so that the insulation layer not only has an insulation function, but also has high temperature resistance and wear resistance, is not easy to break, and has a long service life.
[0026] A protective layer 4 is provided on the outer periphery of the wear-resistant layer.
[0027] Both the connecting layer 2 and the protective layer 4 are paint layers.
[0028] The paint layer is a high-temperature insulating paint layer.
[0029] The thickness of the connecting layer 2 is 0.1-0.5 mm.
[0030] The thickness of the protective layer 4 is 0.1-0.5 mm.
[0031] The thickness of the wear-resistant layer is 1-5 mm.
[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
