POLE GUYING AND BRACING INSTRUCTIONAL GUIDE
For installation or removal of guys, anchors and bracing devices for overhead distribution poles.
Compatible Unit Coding for “G” and “A” Section Guys Guys have been coded according to size and type using a “G” prefix. Special purpose guys and attachments have also been appropriately coded. Single, double, overhead and sidewalk guys are available with individual Compatible Unit code numbers. Primary, secondary and pedestrian guy guards are also available.
Anchors Standard anchors and anchor/rod combinations are coded with an “A” prefix. The numbers and letters in the code designate the sizes and descriptions of the anchoring devices.
Guy/Anchor Combinations Guy and anchor combinations are available by combining the individual numbers to form one Compatible Unit number. This applies to all the recommended single and double down guy combinations with the various types of anchors.
Example: G5 A108 (Compatible Unit no.)
One 5/16” down guy with guy guard One 10” anchor with 8 ft. rod
Bottom guy Top guy with guy guard
G3 5 A108 (Compatible Unit no.)
One 3/8” and one 5/16” down guy with guy guard One 10” anchor with 8 ft. rod

Special Pole Bracing
Special types of pole bracing are provided in this section and have a "G" prefix. Tile pole foundations, butt plate bracing, pole key bracing, push pole bracing, temporary pole bracing and stub pole bracing have been assigned Compatible Unit numbers to allow a variety of pole bracing applications. The numbers are explained in detail on the standard drawings.
Grid Sketch Application
Guy, anchor and pole bracing codes are to be entered in the Miscellaneous section of the grid sketch (lines 13 thru 18) under the point number which represents the pole they are to be installed on.

ESE will maintain program procedures (review NESC for changes), advise and train personnel who
design and build facilites with guys and provide inspection services if requested by responsible
divisions. The Responsible Divisions will assure that designs properly show how guys and guy
insulators are used and where to install them. The line crews that construct the guying must be sure
that the guys are properly grounded or if ungrounded the insulated sections are properly installed.
8512E359.DGN

All guys shall be effectively grounded unless insulated per item No. 5.
b) Down guy - a down guy consists of a wire running from an attachment on a pole to a
rod and anchor installed in the ground.
c) Span or head guy - a span guy consists of a wire running from an attachment on a pole to an
adjacent pole opposing the strain from the line conductors. Insulated guy rod - a device
installed in a guy to maintain adequate electrical clearances, provide safe working space for linemen,
reduce nuisance linetripping from guy contacts with line conductors and protect the public against
possible exposure to an energized guy.
a) Guy - a supporting member fastened between a fixed support and a pole to provide an opposing
force to balance conductor tension(s)acting on the pole.
3). Definitions:
4). Grounding Guy Requirements
To be effectively grounded, guys shall be electrically connected to one or more of the following:
a) Grounded metallic supporting structure (grounded steel pole)
b) An effective ground on a nonmetallic supporting structure (pole ground)
c) A line conductor that has at least four (4) grounds in each mile of line (system neutral)

The placement of insulator(s) in an ungrounded guy is intended to protect the public against a possible

the insulated guy must comply with the following:
All efforts to ground the guy wire must be exhausted prior to installation of the insulated guy section. When
the guy to energized part clearance cannot be obtained,
a). Insulators shall be so placed that if the guy is broken below the insulator or any guy is contacted by an
energized conductor or part, the voltage will not be transferred to other facilities on the structure(s) or below
8’ above ground.
b). Insulators shall be so placed that in case any guy sags down upon another, the insulators will not
become ineffective.
Head guy - Terminated to stub pole, no other electrical facilities adjacent/on the stub pole or between
the guyed and stub pole: The horizontal plane defined by the lowest energized facility shall pass through
the center or upper half of the lowest guy insulator.A check shall be made to determine, under a broken
guy condition (at stub pole), guy hanging vertically, that requirements 5a and 5b are met.
Head guy - Terminated to stub pole, with other electrical facilities adjacent/on the stub pole or between the
guyed and stub pole: In addition to the above check, a check shall be made, under a broken guy condition
(at the guyed pole), guy hanging vertically, that requirements 5a and 5b are met.
Down guy -The horizontal plane defined by the lowest energized facility shall pass through the center
or upper half of the lowest guy insulator.A facility is considered energized if it is at a service voltage
(120 volts) or higher. A check shall be made to determine, under a broken guy condition (at anchor eye),
guy hanging vertically, that requirements 5a and 5b are met.
