Description

Technical Field

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

[0002] Underground cables refer to cables that are often buried underground compared to common overhead lines. Cables are made of one or more mutually insulated conductors covered with an insulating layer and a protective layer, and are used to transmit electricity or information from one place to another. After entering modern society, due to the shortage of urban land, heavy traffic pressure, and urban appearance construction, large cities generally adopt underground cable transmission. Compared with overhead lines, cables have the advantages of small footprint, reliable power transmission, and strong anti-interference ability.

[0003] When wiring underground cables, it is necessary to manually cut and peel off the cable sheath to expose the steel belt, and then fold the steel belt onto the unpeeled cable sheath. However, the existing method of handling the steel belt is relatively cumbersome, and the steel belts need to be folded one by one, which affects the wiring efficiency. Therefore, it is necessary to provide an underground cable to quickly handle the steel belt. Utility Model Content

However, the existing steel belt processing method is relatively cumbersome and the steel belts need to be folded one by one, which affects the connection efficiency.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
