Problems solved by technology

[0003] Power cables are generally used outdoors or buried underground, and there are a lot of electromagnetic waves around us. Some power cables are set in special positions, and there will be many interference devices around, which will affect the transmission of the cables. Furthermore, The power cable itself has strong radiation, and it will also have a great impact on people who are close to the power cable
The cables in the prior art are equipped with copper mesh or steel wire inside to ensure signal transmission. The copper mesh or steel wire is implanted separately, so that a lot of metal is exposed outside at the joint position, which is messy and inconvenient for power supply. Workers work; so these problems need to be solved urgently

Abstract

The invention provides a power cable with a metal mesh structure. The power cable comprises a cable shell and a cable core. The power cable further comprises the metal mesh structure arranged on the inner surface of the cable shell. The metal mesh structure comprises a flexible substrate and a metal mesh arranged on the surface of the flexible substrate; the metal mesh is formed by intersecting firs metal wires and second metal wires; the first and second metal wires are made of conductive material; one side of the metal mesh structure faces the cable shell. According to the power cable, the technical mesh is attached onto the flexible substrate, one inside of the metal mesh faces out, and the metal mesh can be well insulated from the cable core; the metal mesh is well flexible, and no scattered metal wires occur during cutting; metal materials for increasing rigidity and adhesion of the metal mesh structure are added to the metal material, and stability of the metal mesh structure is improved.

Description
