be provided where guy tension exceeds 27 kN 6000 pounds. Guy clamps 152 mm
6 inches in length with three 15.9 mm 5/8 inch bolts, or offset-type guy
clamps, or approved guy grips shall be provided at each guy terminal.
Guy-strain insulators shall be provided in each guy for wood poles.
Multiple-helix screw anchors shall be provided in marshy ground; rock
anchors shall be installed in rock at right angles to guys, elsewhere
anchors shall be of an expanding type, except that power installed screw
anchors of equivalent holding power are acceptable. A half-round [yellow]
[gray] [_____] polyvinyl, fiberglass, or other suitable plastic guy marker,
not less than 2.4 m 8 feet in length, shall be provided at the anchor end
of each guy shown, securely clamped to the guy or anchor at the bottom and
top of the marker. Holding capacities for down guys shall be based on a
lead angle of [45 degrees] [as indicated].

CONDUCTOR INSTALLATION
3.5.1
Line Conductors
Unless otherwise indicated, conductors shall be installed in accordance
with manufacturer's approved tables of sags and tensions. Proper care
shall be taken in handling and stringing conductors to avoid abrasions,
sharp bends, cuts, kinks, or any possibility of damage to insulation or
conductors. Conductors shall be paid out with the free end of conductors
fixed and cable reels portable, except where terrain or obstructions make
this method unfeasible. Bend radius for any insulated conductor shall not
be less than the applicable NEMA specification recommendation. Conductors
shall not be drawn over rough or rocky ground, nor around sharp bends.
When installed by machine power, conductors shall be drawn from a mounted
reel through stringing sheaves in straight lines clear of obstructions.
Initial sag and tension shall be checked by the Contractor, in accordance
with the manufacturer's approved sag and tension charts, within an elapsed
time after installation as recommended by the manufacturer.
3.5.2
Connectors and Splices
Connectors and splices shall be mechanically and electrically secure under
tension and shall be of the nonbolted compression type. The tensile
strength of any splice shall be not less than the rated breaking strength
of the conductor. Splice materials, sleeves, fittings, and connectors
shall be noncorrosive and shall not adversely affect conductors.
Aluminum-composition conductors shall be wire brushed and an oxide
inhibitor applied before making a compression connection. Connectors which
are factory-filled with an inhibitor are acceptable. Inhibitors and
compression tools shall be of types recommended by the connector
manufacturer. Primary line apparatus taps shall be by means of hot line
clamps attached to compression type bail clamps (stirrups). Low-voltage
connectors for copper conductors shall be of the solderless pressure type.
Noninsulated connectors shall be smoothly taped to provide a waterproof
insulation equivalent to the original insulation, when installed on
insulated conductors. On overhead connections of aluminum and copper, the
aluminum shall be installed above the copper.
3.5.3
Conductor-To-Insulator Attachments
Conductors shall be attached to insulators by means of clamps, shoes or tie
wires, in accordance with the type of insulator. For insulators requiring
conductor tie-wire attachments, tie-wire sizes shall be as indicated in
TABLE II.
