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.

The use of the flexible bonding characteristics of the pre-twisted structure to absorb vibration energy is the main method to reduce the vibration of the conductor. Dispersing vibration stress through precise installation location planning is an important way to improve the damping effect. Combining conductor parameters and environmental conditions to select the appropriate helical armor rods for overhead line model is the basis for effective damping.

​Protecting the wire from physical damage and environmental erosion is the most basic purpose of helical armor rods for overhead line. Improving the mechanical properties and operating stability of transmission lines is another purpose of helical armor rods for overhead line. Reducing the operation and maintenance costs and safety risks of transmission lines is an important purpose of helical armor rods for overhead line from the perspective of practical application.

Nowadays, communication lines are an important part of our lives. If there is damage, our network will not be available, which will affect our lives and work. Severe weather such as heavy rains is often the main cause of damage to communication lines, and rainwater can cause lines to malfunction. So if we use armored rods, can we better protect the communication lines? So can its water resistance withstand the test of heavy rains? The content of this article will be explained to you.

In order to ensure long-term stable operation of the product in actual engineering, the following factors have an important impact on the service life of armor rods

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?
