Transmission lines typically operate in various complex environments; therefore, the environmental conditions of the project site are a crucial factor to consider when selecting Prepared Armor Rods.

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.

Helical armor rods, as a type of prefabricated helical protective rod, effectively protect conductors and optical cables.

Helical armor rods for overhead lines play a crucial protective role in high-voltage transmission lines and communication cables, and their material and weather resistance directly affect long-term stability. This article introduces the high-strength alloy, anti-corrosion coating, and application environment of helical armor rods, analyzes their performance under wind vibration, corrosion, and external force damage, and showcases the advantages of our products and our rapid delivery capabilities.

Overhead power and communication lines often face challenges such as wind-induced vibration, thermal expansion and contraction, external abrasion, and corrosion. These factors can cause cable damage, strand breakage, or even system failures. Helical armor rods for overhead line​, also called pre-formed armor rods, provide a simple and effective solution. By tightly wrapping around cables near support points, they distribute stress and absorb vibration, helping to significantly extend the service life of cables.

From the point of view of structure and material, the guard line is made of multiple strands of high-strength aluminum alloy prefabricated into a spiral structure. Each strand is heat-treated and formed, which can make the spiral arc and the outer diameter of the wire highly match. This preformed design is different from the traditional rigid wire protection fittings. Its flexible structure can closely fit the surface of the wire to avoid the local stress concentration of the wire caused by rigid contact.
