The cable may be damaged due to long-term damp, rubber aging, frequent twisting, cutting damage during assembly, and the like. Therefore, the cable needs to be regularly maintained and repaired. During the repair, the cable sheath is first cut open, and the damaged part needs to be cut off. Then, the sheath, steel belt armor, and the like are cleaned. Then, the semi-conductive tape is wound around the damaged part to weaken the concentrated electric field. Finally, the cable is completely wrapped with the insulating tape.

[0003] The prior art, such as the invention disclosed in patent No. CN114825159B, discloses a highway tunnel cable maintenance equipment. The equipment includes a vehicle body, which is divided into a front chamber and a rear chamber. A carrying unit for carrying the cable trench cover is arranged in the front chamber.
