GENERAL RECOMMENDATIONS:
-PROTECTION. PREFORMED Armor Rods are intended to protect against bending, compression, abrasion, 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. As a general guide, the following recommendations may be adopted to the specific conditions.
-Armor Rods are recommended as minimum protection for clamp-type supports or suspensions.
-Line Guards are recommended as minimum protection for hand-tied spans.
-The use of supplementary damping devices, such as Spiral Vibration Dampers, should be considered when conductor vibration is present or expected.
-PLP® Factory Formed Ties are recommended as being superior to armor-hand tie combinations in providing protection from abrasion, and equivalent in providing protection from vibration fatigue.
-ARMOR-GRIP® Suspension is recommended as being superior to armor clamp combinations in providing protection from bending stress, compression stress and abrasion.
-ARMOR RODS RESTORATIVE-REPAIR:
-Armor Rods may be used to restore full conductance and strength to ACSR and aluminum conductors where damage does not exceed approximately 50 percent of the outer strand layer. For standard catalog numbers damage should be located at the "point of support" or within the "midspan area".
**NOTE: When Armor Rods are used to repair damaged aluminum-based conductors, the following application steps are required for optimum electrical repair:
-Step 1: Thoroughly wire-brush damaged conductor for the full length of the Armor Rods to be applied.
-Step 2: Apply a gritted inhibitor to the full length of this area before applying the Armor Rods.**
-TAPPING:
-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.
-APPLICATION-INSPECTION:
-After application of the correct number of rods per set, a slight gap between rods should be present. Consult the General Information Section for detailed explanation.
-Apply no more than one-half the number of rods per set at a time on smaller sizes. On conductors 4/0 and larger, do not attempt to apply more than 4 rods at a time. The alignment of the ends of the rods should be maintained within 2 inches for voltages of 230 KV and lower.
-MATERIAL SELECTION:
-For copper or Copperweld® conductor, Copperweld® or Phosphor Bronze, Armor Rods are recommended when electrical requirements such as tapping or repair are not involved.
