Optimizing cable interlocking armor to enhance cable performance

Optimizing cable interlocking armor to enhance cable performance

As an important part of the cable, interlocking armor plays a vital role in protecting the cable and improving its performance. With the continuous improvement of the power system on the cable reliability requirements, the performance of the interlocking armor also put forward higher requirements. In this paper, we will discuss the application of chain link armor in cable, and put forward some optimization suggestions, in order to provide useful reference for the cable industry.

Interlocking armor is mainly divided into the following types:

· Steel wire braided armor: good flexibility, suitable for cables with large mobility, such as drag chain cables, robot cables, etc.

· steel belt armor: high tensile strength, suitable for fixed laying cables, such as power cables, control cables and so on.

· Copper tape armor: good conductivity, commonly used in shielding electromagnetic interference.

· Stainless steel belt armor: excellent corrosion resistance, suitable for cables in harsh environments.

The role of interlocking armor in the cable

· Mechanical protection: Prevent the cable from mechanical damage such as extrusion, bending and stretching by external force.

· Electromagnetic shielding: Reduce electromagnetic interference and improve the anti-interference ability of cable.

· Anti-corrosion protection: Extend the service life of the cable.

· Improve cable tensile strength: Enhance the mechanical strength of the cable.
