In power transmission line systems, attention is often focused on core components—such as the conductors themselves

Throughout the long-term evolution of transmission lines, conductor protection technology has consistently played a pivotal role.

In overhead transmission line systems, conductors are subjected to various external factors during long-term operation.

To reduce these potential risks, the power industry typically installs Preformed Armor Rods at critical locations. This simple yet highly effective line hardware forms a protective layer on the conductor surface, extending the conductor's service life and improving the overall reliability of the line.

Protective fittings are fittings that improve and protect the mechanical and electrical working conditions of conductors and insulator fitting strings. Mechanical protective fittings refer to fittings installed on conductors for mechanical protection, such as anti-vibration hammers, preformed wires, Preformed Armor Rods, spacers, etc.; mechanical protective fittings for optical cables, such as anti-vibration hammers, Preformed Armor Rods, down conductor clamps, and cable racks. For example, Preformed Armor Rods is a strip of fittings wrapped around the outside of the conductor at the clamp. It is a mechanical protective fitting to prevent breeze vibration. So what effect will the use of preformed protective wire produce?

In the operation and maintenance of power lines, if we continue to use traditional protection methods and refuse to use preformed armor rods, we will face multiple risks and challenges. Data shows that a provincial power grid insisted on using traditional protection methods, and spent 38 million yuan on maintenance costs due to wind vibration damage alone last year, while the regional failure rate of new technologies adopted during the same period dropped by 72%. Industry experts warn: "Refusing technology upgrades may seem to save initial investment, but in fact it will lead to higher cycle costs." With the improvement of grid reliability requirements, sticking to outdated technology will become increasingly difficult to meet the safety needs of modern power systems.
