    Armor Rods are intended to protect against bending, compression, abrasion, and arc-over, and to provide repair. The degree of protection needed on a specific line depends upon a number of factors such as line design, temperature, tension, exposure to wind flow, and vibration history on similar construction in the same area.

    Armor rods are recommended as minimum protection for clamp type supports or suspensions. Line Guards on the other hand are recommended as minimum protection for hand tied spans. Armor rods may be used to restore full conductance and strength to ACSR and aluminum conductors where damage does not exceed approximately 50% of the outer strand layer.

    Tapping over applied aluminum Armor Rods is permissible. Where it is known that tapping clamps will be installed over Armor rods, it is recommended that the conductor be thoroughly wire brushed clean, then an inhibitor be applied.

    Also known as preforms, helical fittings come in a range of designs for specific applications.

    Designed to grip uniformly to prevent distortion of the conductor, preforms also offer a unique design that eliminates bolts, nuts, washers and other components, they simply wrap on and grip under tension. With colour-coded markings based on size, it is easy to select the correct part.

    Now with user-friendly labelling, a clear part number, colour, cable OD range, conductor names and a barcode are all included on the strong water-resistant label which is attached to each and every Helical fitting that leaves our store.

    Automatic Production Line Of Preformed Armor Rod Forming

    Armor rods are preformed rods used for wrapping around the outer layer of wires and mounting on the boat shaped wire clamp, in order to improve the conductor rigidity, decrease conductor vibration and protect damaged conductors by preventing the damaged area from expanding. Also, the protective rods can be wrapped in aluminum conductor and installed on the post insulator to increase the conductor rigidity and play a role in reducing vibration.


    a. The armor rod’s material should be the same as the conductor.
    b. The armor rods are installed easily without any special tools.
    c. The armor rod has good anti-vibration performance and high flexibility. It can protect the cable and extend the system life.

    Product specificationCautions:
    When repairing the conductor, the damaged area should be no more than 7~25% of total area. (ASCR should not damage the steel core.) When calculating the damaged area, take the total aluminum wire area for the base.
