In recent years, it has also been widely used in high-rise buildings, airports, docks, subways and other places.

[0003] For example, the Chinese invention patent / utility model patent (application number: CN216849409U) discloses a tensile-resistant mineral-insulated PVC-coated cable, which relates to the field of cable technology. This tensile-resistant mineral-insulated PVC-coated cable includes a cable body, which is composed of a protective layer, a buffer layer, an inner layer, a support tube, a cable core, a support plate, and mineral filler.

[0004] Although the aforementioned patent can enhance the tensile strength of the cable body, the aforementioned device still has the following problems: during the use of the device, because the device enhances the tensile strength through a number of rigid components, it reduces the flexibility of the cable, resulting in a large bending radius and difficulty in laying, especially in confined spaces; secondly, the multi-layer complex structure increases the weight of the cable and the production cost. Therefore, we have made improvements to this and proposed a tensile-resistant mineral cable. Utility Model Content

[0005] The purpose of this invention is to solve the current problems of BBB.

The stabilizing layer includes a first support layer, a second support layer, a first reinforcing layer, and a second reinforcing layer. The first reinforcing layer and the second reinforcing layer are disposed between the first support layer and the second support layer.

[0007] As a preferred technical solution of this application, the first reinforcing layer and the second reinforcing layer form a V-shape.

[0008] As a preferred technical solution of this application, a heat dissipation groove is provided on the outer surface of the cable body, and the heat dissipation groove is spirally arranged on the outer surface of the cable body.

[0015] In the scheme of this application:

[0016] 1. By using a fiber braided mesh layer and a silicone layer, the cable stiffness caused by the rigid support structure is eliminated, significantly reducing the minimum bending radius and making installation convenient. At the same time, high-performance fibers such as aramid and ultra-high molecular weight polyethylene are selected, whose specific strength is much higher than that of steel. While providing the same or even higher tensile strength, the cable weight is greatly reduced. The silicone layer can protect the wire core, conduct and dissipate the heat generated by the wire core, and buffer external impact forces, so that the wire core can be better protected.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A tensile-resistant mineral cable includes a cable body 1, which includes an outer layer 2, a reinforcing layer 3, an inner layer 4, and a conductor 5. The reinforcing layer 3 is disposed on the inner surface of the outer layer 2, and the inner layer 4 is disposed on the inner surface of the reinforcing layer 3. A silicone layer 6 is fixedly connected inside the inner layer 4. The silicone layer 6 is made of silicone. The conductor 5 is disposed inside the silicone layer 6. The silicone layer 6 can protect the conductor 5, conduct and dissipate the heat generated by the conductor 5, and buffer external impact forces, so that the conductor 5 can be better protected. The reinforcing layer 3 includes a first support layer 11, a second support layer 12, a first reinforcing layer 13, and a second reinforcing layer 14. The first reinforcing layer 13 and the second reinforcing layer 14 are disposed between the first support layer 11 and the second support layer 12, forming a V-shape. The first reinforcing layer 13 and the second reinforcing layer 14 can more stably support the interior of the cable body 1 and improve the internal strength of the cable body 1.

[0030] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown in the figure, a heat dissipation groove 7 is provided on the outer surface of the cable body 1. The heat dissipation groove 7 is spirally arranged on the outer surface of the cable body 1. The heat dissipation groove 7 increases the contact area between the outer surface of the cable body 1 and the external environment, and enhances the heat dissipation efficiency of the cable body 1 to a certain extent.

[0031] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown in the figure, the outer layer 2 includes a base layer 15, a flame-retardant layer 16, and a wear-resistant layer 17. The flame-retardant layer 16 is disposed on the outer surface of the base layer 15, and the wear-resistant layer 17 is disposed on the outer surface of the flame-retardant layer 16. The flame-retardant layer 16 is made of flame-retardant material, which can improve the flame retardancy of the cable body 1. The wear-resistant layer 17 is made of anti-corrosion and wear-resistant film, which can extend the service life of the cable body 1. The inner surface of the base layer 15 is fixedly connected to the outer surface of the second support layer 12.

[0032] Example 2

[0033] The tensile-resistant mineral cable provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 As shown in the figure, the inner layer 4 includes an insulating layer 8, a fiber woven mesh layer 9, and a mineral layer 10. The fiber woven mesh layer 9 is disposed on the outer surface of the insulating layer 8, and the mineral layer 10 is disposed on the outer surface of the fiber woven mesh layer 9. The outer surface of the mineral layer 10 is fixedly connected to the inner surface of the first support layer 11.

[0034] The fiber braided mesh layer 9 is made of high-strength synthetic fiber braided mesh. The fiber material of the fiber braided mesh layer 9 is extremely soft, which completely solves the problem of cable stiffness caused by rigid support structure, greatly reduces the minimum bending radius, and facilitates laying. At the same time, high-performance fibers such as aramid and ultra-high molecular weight polyethylene are selected, whose specific strength is much higher than that of steel. While providing the same or even higher tensile strength, it greatly reduces the weight of the cable.

[0035] The tensile-resistant mineral cable provided by this utility model is used as follows: the silicone layer 6 can protect the wire core 5, conduct heat generated by the wire core 5, and buffer external impact forces, so that the wire core 5 can be better protected.

[0036] The first reinforcing layer 13 and the second reinforcing layer 14 form a V-shape, which can more stably support the interior of the cable body 1 and improve the internal strength of the cable body 1.

[0037] The fiber material of the 9th layer of fiber braided mesh is extremely soft, which completely solves the problem of cable stiffness caused by rigid support structure, greatly reduces the minimum bending radius, and makes laying convenient. At the same time, high-performance fibers such as aramid and ultra-high molecular weight polyethylene are selected, whose specific strength is much higher than that of steel. While providing the same or even higher tensile strength, it greatly reduces the weight of the cable.

[0038] The flame retardant layer 16 can improve the flame retardancy of the cable body 1 to a certain extent, and the wear-resistant layer 17 is made of anti-corrosion and wear-resistant film. The wear-resistant layer 17 can extend the service life of the cable body 1 to a certain extent.
