Description

Technical Field

[0001] The utility model relates to the technical field of power cables, in particular to an easily identifiable digital power cable. Background Art

[0002] Digital cable refers to a device composed of several or several groups of wires that can be used for signal transmission. With the development of the 5G information age, corresponding 5G digital cables will also be used for signal transmission. Power cables are commonly used in urban underground power grids, power station lead-out lines, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing.

[0003] The exterior of existing power cables is usually set as a smooth thin-layer wear-resistant structure, which has poor wear resistance. During the movement and laying of the cables, personnel pull the cables with great strength, which can easily cause serious wear on the cables. The appearance of existing power cables is relatively uniform, and the structure is relatively fixed, which is not easy to identify. In addition, the buffering performance of existing power cables is poor, which can easily cause the cables to fall from high places during laying, thereby causing damage to the cables. For this reason, we propose an easily identifiable digital power cable. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 The utility model provides a technical solution: an easily identifiable digital power cable, comprising a core 1, the core 1 has three strands, and an insulating layer 2 is arranged on the outside of the core 1, an inner supporting layer 4 is arranged on the outside of the insulating layer 2, a filling layer 3 is arranged on the outside of the inner supporting layer 4 and located outside the insulating layer 2, a shielding layer 5 is arranged on the outside of the inner supporting layer 4, and a buffer layer 6 is arranged on the outside of the shielding layer 5.

[0023] It should be noted that the setting of the insulating layer 2 can prevent internal current from reaching the outside, preventing human body contact with the motor during cable laying. The insulating layer 2 can prevent heat conduction and play a certain role in heat insulation and thermal insulation. The setting of the shielding layer 5 can effectively block external electromagnetic interference from entering the core 1. The setting of the buffer layer 6 can have a good buffering and shock-absorbing effect, which is beneficial to protecting the cable.

[0024] A high temperature resistant layer 7 is arranged outside the buffer layer 6, and a waterproof layer 8 is arranged outside the high temperature resistant layer 7. An outer supporting layer 9 is fixedly connected to the outer side of the waterproof layer 8, and a wear-resistant sleeve 10 is arranged outside the outer supporting layer 9.

[0025] It should be noted that the utility model can prevent internal current from reaching the outside through the setting of the insulating layer 2, and prevent human body contact with the motor incident during cable laying. The insulating layer 2 can prevent heat conduction and play a certain role in heat insulation and thermal insulation. The setting of the shielding layer 5 can effectively block external electromagnetic interference from entering the core 1, and it can also reduce crosstalk and cross coupling between signals to ensure the stability and reliability of signal transmission. During cable laying, if the cable falls from a height, the inner support layer 4, the support rod 12, the buffer spring 13 and the outer support layer 9 can provide good support and shock absorption and buffering performance, and can better ensure the function of the core 1. The high temperature resistant layer 7 can isolate external heat and protect the core 1. At the same time, during cable laying, when the cable is repeatedly pulled on the supporting surface, the wear-resistant sleeve 10 and the wear-resistant strip 11 can have a good wear-resistant effect and protect the cable. At the same time, the colored strip 14 on the wear-resistant strip 11 can have a marking and eye-catching effect, and the identification code 15 is set to make it easy for people to identify the cable.

[0026] Wear-resistant strips 11 are equidistantly arranged on the outer side of the wear-resistant sleeve 10, and the wear-resistant strips 11 are in the shape of racks.

[0027] It should be noted that the wear-resistant strip 11 is in the shape of a rack. When pulling the cable, the wear-resistant strip 11 is the first to contact the supporting surface. The cooperation of multiple wear-resistant strips 11 enhances the wear-resistant effect and keeps the wear-resistant sleeve 10 intact, which is conducive to better protecting the inside of the cable.

[0028] The outer sides of the wear-resistant strips 11 are all provided with V-shaped grooves, and the V-shaped grooves are fixedly connected with coloring strips 14, which are triangular prism rod-shaped structures.

[0029] It should be noted that the colored strip 14 is fixedly arranged inside the V-shaped groove of the wear-resistant strip 11, which is more eye-catching visually and easy to identify the cable.

[0030] The buffer layer 6 includes a support rod 12 and a buffer spring 13. The outer side of the inner support layer 4 is equidistantly fixedly connected with the support rod 12, and the end of the support rod 12 passes through the buffer layer 6, the high temperature resistant layer 7 and the outer support layer 9. The end of the support rod 12 extends into the wear-resistant sleeve 10. The buffer layer 6 is provided with a buffer spring 13 located on the outer side of the support rod 12.

[0031] It should be noted that during cable laying, if the cable falls from a height, the coordinated arrangement of the inner support layer 4, the support rod 12, the buffer spring 13 and the outer support layer 9 can provide good support and shock-absorbing performance, and can better ensure the function of the core 1.

[0032] The surface of the wear strip 11 is provided with an identification code 15 .

[0033] It should be noted that digitized cables are usually equipped with unique marking codes, which can be identified and traced through the identification code 15.

[0034] A waterproof layer 8 is provided between the high temperature resistant layer 7 and the outer supporting layer 9 , and the supporting rod 12 passes through the waterproof layer 8 .

[0035] It should be noted that the provision of the waterproof layer 8 can protect the cable from being attacked by rainwater and prevent moisture from entering the interior and damaging the core 1.

[0036] The wear strip 11 and the wear sleeve 10 are an integrated structure.

[0037] It should be noted that the coordinated arrangement of the wear-resistant sleeve 10 and the wear-resistant strip 11 can achieve a good wear-resistant effect and is beneficial to protecting the cables.
