SPARK FITTINGS Products Range:

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. (91 m). Manufactured from either aluminum alloy, Alumoweld®, or galvanized steel, they are designed for use with ACSR, AAC, AAAC, ACSS, SSAC, TW Types and ACAR conductors as well as Alumoweld®and steel ground wire. All rod sets are manufactured with right-hand lay as standard for aluminum-based material and left hand lay for Alumoweld and steel ground wire.

Armor Rods Features:
-Color coded for ease of identification
-Full strength restoration when less than 50% of the outer strands are broken
-Special ends for high voltage application

AFL Armor Rods Product Description
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.

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 power fittings number.
