OVERHEAD CONDUCTORS
**************************************************************************
NOTE: For LANTNAVFACENGCOM projects, do not use
"copper clad steel" or "aluminum conductor steel
reinforced (ACSR)."
**************************************************************************
Conductors of bare [copper] [aluminum (AAC)] [aluminum alloy (AAAC)]
[copper clad steel] [aluminum conductor steel reinforced (ACSR)] of sizes
and types indicated.
2.6.1
Solid Copper
ASTM B 1, ASTM B 2, and ASTM B 3, hard-drawn, medium-hard-drawn, and
soft-drawn, respectively. ASTM B 8, stranded.
2.6.2
Aluminum
ASTM B 231/B 231M.
2.6.2.1
Aluminum Alloy
ASTM B 397 or ASTM B 399/B 399M.
2.6.2.2
Steel Reinforced
ASTM B 232/B 232M, aluminum.
2.6.3
Copper-Clad Steel
ASTM B 228.
2.7
NEUTRAL-SUPPORTED SECONDARY AND SERVICE DROP CABLES
**************************************************************************
NOTE: The term "secondary," for our general
purpose, means either bare or insulated conductors
installed between poles and operated at the
utilization voltage. Bare conductors should be
utilized on long span, open wire design when a
neutral-supported secondary cable is not appropriate
due to weight. When using bare conductors for
secondary applications use the above paragraph
entitled "Overhead Conductors". "Services" are
insulated conductors extending from a pole to the
metering point or service entrance connection at the
utilization point. Minimum conductor size for
aluminum, aluminum alloy, or ACSR shall be No. 4 AWG
and for copper, No. 6 AWG. For LANTNAVFACENGCOM
projects, do not use ACSR.
