**************************************************************************
Insulated medium-voltage line conductors shall be of the factory-assembled,
messenger-supported type, having a rated circuit voltage of [5] [15] [25]
[_____] kV, and a 133 percent insulation level. Conductor material shall
be [_____]. Insulation shall be [cross-linked thermosetting polyethylene
(XLP) conforming to [_____]] [ethylene-propylene-rubber (EPR) conforming to
[_____]] [_____]. Messengers shall be zinc-coated steel,
aluminum-clad-steel, copper-clad-steel, or composite-copper and copper-clad
steel.

LOW-VOLTAGE LINES
**************************************************************************
NOTE: Due to both space requirements and the
unattractive appearance, line conductors on
secondary racks will be limited to special
circumstances.
**************************************************************************
Low-voltage line conductors shall be of the neutral-supported secondary and
service drop type with [thermoplastic insulation in accordance with
[_____]] [cross-linked thermosetting polyethylene (XLP) insulation in
accordance with [_____]] [weather-resistant polyolefin-covered type
conforming to ICEA S-70-547]. Neutral-supported secondary and service drop
conductors shall be [insulated copper with bare hard-drawn-copper or
copper-clad steel neutrals] [insulated aluminum with bare 1350 alloy
aluminum or ACSR neutrals]. Conductors on secondary racks may be provided
in lieu of neutral-supported cable for pole line circuits where necessary
clearances are available.
2.8
POLES AND HARDWARE
**************************************************************************
NOTE: Use "class" for wood poles and "strength" for
concrete and steel poles. Follow local utility
practice regarding grounding metallic items on
poles, after coordination with local DPW/BCE.
Specify clearances and climbing space in accordance
with IEEE C2 or applicable state code.
**************************************************************************
Poles shall be of lengths and [classes] [strengths] indicated.
2.8.1
Wood Poles
**************************************************************************
NOTE: Waterborne preservatives should not be used
in humid and/or termite infested areas.
**************************************************************************
Wood poles shall comply with ATIS O5.1, and shall be pressure treated in
accordance with AWPA C4, with creosote conforming to AWPA P1/P13or with
oil-borne preservatives and petroleum conforming to AWPA P8 and AWPA P9,
respectively, and waterborne preservatives conforming to AWPA P5.
Waterborne preservatives shall be either chromated or ammoniacal copper
arsenate. Any species listed in ATIS O5.1 for which a preservative
treatment is not specified in AWPA C4, shall not be used; northern white
