| Formed Wire: Armor Rods |
|
Armor rods are designed to protect the conductor by reducing bending, compression, and abrasion at the support point. Protection against flashover damage is also provided. Armor rods are recommended as protection for spans greater than 300 ft. (91m). Manufactured from either aluminum alloy, Alumoweld®, or galvanized steel, they are designed for use with ACSR, AAC, AAAC, and ACAR conductors as well as Alumoweld and steel ground wire. All rod sets are manufactured with right-hand lay as standard.

Features:
Color Coded and Center Marked
For ease of identification to conductor size, the armor rods are color coded in the center of the rod. This feature also assists in alignment of the rods during installation.
Repair Damage
When no more than 50% of the outside strands on an ACSR or aluminum conductor have been damaged outside the support point, armor rods may be used to restore 100% of the rated conductance and strength of the line.
Vibration Protection
Installing armor rods improves the conductor’s ability to withstand the fatigue forces associated with aeolian type vibration. They do not function as vibration control devices. For assistance in determining the proper vibration protection, contact the ACA Technical Support Team or visit our website at www.Vibrec.com.
Tap Over
Armor rods may be tapped over on ACSR and aluminum conductor, but not on Alumoweld, or steel ground wire. Where tapping is used, it is strongly recommended that the conductor is thoroughly wire brushed and an oxide inhibitor be applied.
Extra High Voltage Applications
For 345 kV and above, the armor rod ends are modified to eliminate Corona effects and include a suffix of ‘EHV’ at the end of the product number.
Customized Armor Rods
For armor rods with special requirements, such as longer lengths or non-standard lay direction contact the ACA Technical Support Team at 1.800.866.7385.
