[0006] Preferably, a plurality of rubber strips are arranged at intervals along the circumferential direction in the buffer function layer, and buffer rubber is provided between the plurality of rubber strips.

[0007] Preferably, a cavity is provided in the rubber strip, and the cavity is filled with capsaicin.

[0008] Preferably, the outer layer of the cable core is arranged with a loose tube, a plurality of conductors are arranged in the loose tube, and a water-blocking material is filled between the plurality of conductors and the loose tube.

[0009] Preferably, the outer sheath layer consists of a corrosion-resistant layer, a flame-retardant layer and a thermal insulation layer, the corrosion-resistant layer is arranged on the outer surface of the flame-retardant layer, and the flame-retardant layer is arranged on the outer surface of the thermal insulation layer.

[0010] Preferably, the water-blocking material is fiber paste, and the material of the loose tube is polybutylene terephthalate or modified polypropylene.

[0011] Preferably, the buffer functional layer is formed by a plurality of rubber strips and a plurality of buffer rubbers being twisted alternately along the steel wire armor layer as the axis.

[0012] The beneficial effects of the present invention are:

[0013] The present invention is provided with a plurality of air bags and foam glue inside the air bags, so that after the outer sheath layer is gnawed by rodents or damaged by external impact, the air bags in the protective repair layer at the gnawed or damaged position can be damaged, and the foam glue in the air bags can flow out from the damaged position and react with the air to expand, so that the damaged position can be quickly filled, and the outer sheath layer can be protected after the foam glue expands and hardens in contact with the air, and the subsequent protection capability of the damaged position of the outer sheath layer can be guaranteed, thereby improving the protection of the cable body and guaranteeing the service life of the cable body. At this time, the air bags at the remaining positions of the protective repair layer are still in a waiting state to take effect, and the safety of the cable body is continuously guaranteed.

[0014] The present invention can well buffer the impact force from the outside through the buffer functional layer provided. When impacted, the impact force can be well buffered by the deformation of the buffer rubber and the rubber strip, and the impacted position of the cable body can be restored by the elasticity of the buffer rubber and the rubber strip. The overall puncture resistance of the cable body can be improved to a certain extent through the setting of the steel wire armor layer, thereby further ensuring the service life of the cable body. The flexible filler layer can be set to well protect the cable core when the cable body is impacted by external force to avoid damage to the cable core. The water-blocking material in the cable core can protect the conductor under external force impact while preventing longitudinal water seepage, thereby further improving the service life of the cable body. Since the cavity of the rubber strip is filled with capsaicin, it can provide a certain rat-proofing effect while protecting the cable body. When rats gnaw one of the rubber strips, the capsaicin in the cavity of the rubber strip will emit a spicy smell, which makes the rats have a certain fear. Under normal conditions, the capsaicin is enclosed in the rubber strip, and the sealing process will not emit odor, thereby ensuring a long-term rat-proofing effect.
