Description

Technical Field

[0001] The utility model relates to the technical field of high-performance cables, in particular to a cable with high insulation strength. Background Art

[0002] A cable usually consists of one or more mutually insulated conductors and an outer insulating protective layer, which transmits electricity or information from one place to another. When an ordinary cable is dragged or bent forcefully during laying, the core of the cable may be damaged or even broken, posing a safety hazard during use. When the insulating layer of the cable is exposed to high temperature, the insulating layer will melt, and the insulating medium between the conductors will be lost, resulting in a short-circuit accident.

[0003] Based on this, a cable with high insulation strength is now provided to solve the problems existing in the existing cables. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the objectives, technical solutions, and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, as Figures 1 - 5As shown in the figure, an insulating high-strength cable includes three parallel cores 101. An insulating layer 201 is provided on the surface of the core 101. A flame-retardant insulating layer 202 is provided on the outer surface of the insulating layer 201. A shielding layer 203 is provided on the outer surface of the flame-retardant insulating layer 202. A first wear-resistant layer 204 is provided on the outer surface of the shielding layer 203. The three cores 101 are arranged in a triangle. A steel core 301 parallel to the cores 101 is provided at the middle position among the three cores 101. A rubber filler is provided between the steel core 301 and the three cores 101. A wrapping layer 401 is provided outside the three cores 101. A second wear-resistant layer 402 is provided on the outer surface of the wrapping layer 401. A waterproof layer 403 is provided on the outer surface of the second wear-resistant layer 402. An anti-corrosion layer 404 is provided on the outer surface of the waterproof layer 403. An outer protective layer 405 is provided on the outer surface of the anti-corrosion layer 404. A reinforcing mesh 406 is provided inside the outer protective layer 405.

[0026] In this embodiment, the steel core 301 improves the overall tensile strength of the cable. The flame-retardant insulating layer 202 reduces the risk of short circuit caused by the high-temperature melting of the insulating layer 201 on the surface of the core 101. The reinforcing mesh 406 provided inside the outer protective layer 405 improves the tensile resistance and torsional resistance of the outer protective layer 405, and improves the structural strength of the cable.

[0027] In one embodiment, as Figure 2 and Figure 4 shown, the flame-retardant insulating layer 202 is composed of a refractory mica tape wound around the outer surface of the insulating layer 201, which is insulating, flame-retardant and fire-proof.

[0028] In one embodiment, as Figure 2 and Figure 4 shown, the shielding layer 203 is a copper wire braided mesh coated on the outer surface of the flame-retardant insulating layer 202, which can prevent the cable from being electromagnetically interfered and prevent the cable from generating electromagnetic interference to other devices.

[0029] In one embodiment, as Figure 1 shown, the rubber filler includes rubber strips 302 evenly distributed inside the wrapping layer 401 and parallel to the cores 101. The rubber strips 302 are made of thermoplastic polyurethane elastomer rubber, which provides support for the cores 101 and the insulating layer 201 to prevent displacement. The rubber strips 302 themselves have elasticity, and when the cable is bent, the rubber strips 302 are deformed to protect the cores 101 from being damaged.

[0030] In one embodiment, as Figure 4 shown, the wrapping layer 401 is made of polytetrafluoroethylene, which wraps the cores 101, the steel core 301 and the rubber strips 302 into a column shape to enhance the structural stability, and also has a flame-retardant function.

[0031] In one embodiment, asFigure 5 As shown, the outer protective layer 405 is made of wear-resistant rubber material, so that the outer surface of the cable is not easily worn during laying and use.

[0032] In one embodiment, as Figure 3 and Figure 5 shown, the reinforcing mesh 406 is an aramid braided mesh, which is arranged inside the outer protective layer 405 to improve the tensile strength and torsional resistance of the outer protective layer 405 and better protect the internal battery cell 101.

[0033] The above embodiment discloses an insulating high-strength cable. Among them, the insulating layer 201 provides comprehensive insulation protection for the battery cell 101. The flame-retardant insulating layer 202 plays a role in flame retardancy and insulation when the insulating layer 201 is damaged or melted, reducing the possibility of direct short-circuit accidents. The shielding layer 203 provided separately on each battery cell 101 prevents the battery cell 101 from generating electromagnetic interference to the outside and can also prevent the outside from generating electromagnetic interference to the cable. When the cable is bent, there is friction between the battery cell 101 and the outer protective layer of the cable. The first wear-resistant layer 204 provided outside the shielding layer 203 protects the shielding layer 203 to prevent the shielding layer 203 from being damaged by friction with the wrapping layer 401 when the cable is bent. The wrapping layer 401 wraps three battery cells 101, the steel core 301 and the rubber strips 302 evenly distributed in the wrapping layer 401 into a columnar whole. The waterproof layer 403 prevents liquid from contacting the wrapping layer 401 and its interior and affecting the structural stability. The anticorrosive layer 404 prevents the waterproof layer 403 from being corroded and damaged. The reinforcing mesh 406 improves the tensile and torsional resistance of the outer protective layer 405 and improves the structural stability of the cable.

[0034] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
