[0015] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0016] Please refer to Figures 1-3 , the present invention provides a technical solution.

[0017] Embodiment 1: Please refer to the attached Figures 1-3 , in the specific implementation process, a protective cable for electrical equipment in a thermal power plant includes: a cable body 1 and a protective structure; the protective structure is installed on the cable body 1; The protective structure includes: a protection component and a wear-resistant component; The protection component is installed on the outer side of the cable body 1, and the wear-resistant component is installed on the protection component; The cable body 1 includes: a graphene wire core 2, a grounding wire 3, a filling layer 4, an insulating sleeve 5, a shielding sleeve 6; The graphene wire core 2 is embedded in the shielding sleeve 6, the shielding sleeve 6 is installed in the insulating sleeve 5, the grounding wire 3 is embedded in the insulating sleeve 5, and the filling layer 4 is filled in the insulating sleeve.

[0018] It should be noted that the cable conducts electricity and supplies power through the graphene wire core 2 inside the cable body 1. During the power supply process of the graphene wire core 2, an electromagnetic effect will be generated. Therefore, an electromagnetic shielding sleeve 6 needs to be arranged outside the graphene wire core 2 for shielding to prevent the magnetic field generated by the graphene wire core 2 during use from affecting external devices. Since the cable may be bent during use, resulting in the exposure of the internal graphene wire core 2, a grounding wire 3 is arranged inside the body to lead out the leaked electricity, and at the same time, the filling layer 4 inside the cable fills and isolates the internal structure to protect the graphene wire core 2.

[0019] Preferably, furthermore, the filling layer 4 is a flame-retardant flexible filler.

[0020] It should be noted that the filling layer 4 being a flame-retardant flexible filler can protect the internal structure during the bending process of the cable, and at the same time prevent the cable from overheating and catching fire during long-term use.

[0021] Preferably, furthermore, the protection component includes: a protection frame 7 and a protective sleeve 8; The protection frame 7 is installed outside the cable body 1, and the protective sleeve 8 is sleeved on the protection frame 7.

[0022] It should be noted that the single cable body 1 has insufficient anti-extrusion deformation strength. Therefore, a protection frame 7 with an annular wavy structure is arranged outside the cable body 1 to protect the cable, increasing the compressive capacity of the cable. At the same time, the protective sleeve 8 arranged outside the protection frame 7 protects the protection frame 7 to prevent the protection frame 7 from being worn and unable to produce a good protection effect.

[0023] Preferably, furthermore, the protection frame 7 is of an annular wavy structure.

[0024] It should be noted that the protection frame 7 of the annular wavy structure enables the protection frame 7 to withstand greater pressure, ensuring the compressive resistance of the cable and increasing its mechanical strength.

[0025] Preferably, furthermore, a metal mesh is arranged inside the protective sleeve 8.

[0026] It should be noted that the arrangement of the metal mesh inside the protective sleeve 8 further increases the anti-deformation ability of the protective sleeve 8.

[0027] Preferably, furthermore, the wear-resistant component includes: a wear-resistant frame 9 and rolling beads 10; The wear-resistant frames 9 are evenly installed on the outer side of the protective sleeve 8, and the rolling beads 10 are evenly embedded in the wear-resistant frames 9.

[0028] It should be noted that since the cable is often pulled during use, it will cause friction between the cable and the ground or pipeline, resulting in damage to the cable, exposing the internal structure, causing damage or loopholes in the cable, and posing a safety hazard. Therefore, a wear-resistant frame 9 is evenly arranged outside the cable. After the cable is placed, the rolling beads 10 on the wear-resistant frame 9 come into contact with the ground or pipeline. At the same time, the adjacent wear-resistant frames 9 will lift the cable, so that the cable will not come into contact with the ground or pipeline. While protecting the cable, the rolling beads 10 on the wear-resistant frame 9 reduce the friction generated when the cable moves, saving manpower in laying the cable.

[0029] Preferably, furthermore, the wear-resistant frame 9 is made of epoxy resin glue.

[0030] It should be noted that the wear-resistant frame 9 made of epoxy resin glue has higher plasticity.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
