Description

Technical Field

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

[0002] Graphene is a carbon nanomaterial with excellent optical, electrical and mechanical properties. It has important application prospects in materials science, micro-nano processing, energy, biomedicine and drug delivery. Adding graphene to manufacture cables with excellent performance is also one of the application prospects of graphene. During the laying process of cables, a cable connection structure must be used to connect the two cables.

[0003] There are many types of cable connection structures currently available on the market, but most of the existing cable connection structures directly rely on the metal core of the cable to bear the main tensile force, resulting in weak tensile strength of the cable at the connection. When erected in the air, due to gravity, wind and other reasons, there will be tension on both sides of the cable joint, which will cause the joint to loosen and have poor contact; the existing cable connectors have poor sealing performance, which can easily cause the cable to be damaged by moisture, and there are also great safety hazards when the cable comes into contact with moisture. In view of this, there may be technical means to solve the above problems in the prior art, but this case intends to provide an alternative or replacement technical solution. Utility Model Content
