Armor Rods
Armor rods shall be provided for AAC, AAAC, and ACSR conductors. Armor
rods shall be installed at supports, except armor rods will not be required
at primary dead-end assemblies if aluminum or aluminum-lined zinc-coated
steel clamps are used. Lengths and methods of fastening armor rods shall
be in accordance with the manufacturer's recommendations. For span lengths
of less than 61 m, 200 feet, flat aluminum armor rods may be used. Flat
armor rods, not less than 762.0 micrometers by 6.4 mm 0.03 by 0.25 inch
shall be used on No. 1 AWG AAC and AAAC and smaller conductors and on No. 5
AWG ACSR and smaller conductors. On larger sizes, flat armor rods shall be
not less than 1.3 by 7.6 mm. 0.05 by 0.30 inches. For span lengths of 61 m
200 feet or more, preformed round armor rods shall be used.
3.1.6.5
Ties
Provide ties on pin insulators tight against conductor and insulator and
ends turned down flat against conductor so that no wire ends project.
3.1.6.6
Reinstalling Conductors
**************************************************************************
NOTE: Sag tables are usually available from
conductor manufacturers. For projects which entail
considerable length of overhead line, sag tables for
the particular line as designed shall be indicated.
**************************************************************************
Existing conductors to be reinstalled or resagged shall be strung to
"final" sag table values indicated for the particular conductor type and
size involved.
3.1.6.7
New Conductor Installation
**************************************************************************
NOTE: Sag tables are usually available from
conductor manufacturers. For projects which entail
considerable length of overhead line, sag tables for
the particular line as designed should be indicated.
Use "indicated" on LANTNAVFACENGCOM projects.
**************************************************************************
String new conductors to "initial" sag table values [indicated]
