SCOPEThis section covers selection of down guys, span guys, sidewalk guys, push braces and anchors. Theselections are based upon wood strengths, guy component strengths, anchor strengths and soil holding powerof anchors.DEFINITIONS (Taken from The Lineman's and Cableman's Handbook, Seventh Edition)1. Down GuyConsists of a wire running from the attachment near the top of the pole to a rod and anchor installed in theground.2. Span GuyConsists of a guy wire installed from the top of a pole to the top of an adjacent pole to remove the strain fromthe line conductors.Span GuyInsulatorRev 2: Added definitions and updated to 2007 NESC.CONSTRUCTION STANDARDSREVISIONSDATE ENGR OPSR12/22/00JEH22/24/11CMAHGUY & ANCHOR SELECTIONPAGE:1of7GCAD FILE:APP:GDATE:GGWSECTION4/1/86700

GENERAL1. Guyinga) Guying assemblies include down, span and sidewalk types. A push brace consisting of a pole andattachment fittings may be used in place of tensioned wire guying only where tension guying is impossible byreason of location or rights-of-way.b) Guying requirements can often be advantageously combined on a deadend pole, a span or more away byextending the circuit or by use of span guys in order to provide a reduced combined guying load on the samepole. A sidewalk guy is an expensive method of guying and provides limited support, particularly on taller poles,due to the comparatively short guy lead. DO NOT use a sidewalk guy if a down or span guy is possible.c) Guy assemblies are designed for the maximum allowable load which may be supported by the pole and therelated hardware. Heavy duty guying will normally require the use of multiple guying attachments.d) A guy marker shall be used on all down guy and sidewalk guy locations. A minimum of one marker peranchor is required. It should be noted that guy markers DO NOT PROTECT OR "GUARD" a down/sidewalkguy, but rather warn the public of its presence.2. Sidewalk Guy InsulationSidewalk guys shall have guy insulators installed in the guy strand above the horizontal guy strut. The breakersshould be at a point that will allow at least 6" clearance between the breaker and the strut attachment to thepole, should the guy wire become broken.3. Grounded GuysGrounded guys shall not be used. All guys on transmission and distribution circuits shall have insulationsections (Johnny balls or fiberglass rods) installed on all new and rebuilt circuits. Grounded guys are to bereplaced by insulated guys when work is done on that pole.4. Application of Guy InsulatorsIt is impractical to show every NESC requirement for applying guy strain insulators. A clear understanding of therules will provide for the correct applications. These guidelines will help in understanding the requirements.Guideline 1 (see figure #1) - All down guys shall have a minimum of one guy insulator. (NESC 215C2)Guideline 2 - All span guys will have a minimum of two guy insulators. (NESC 215C5)Guideline 3 (see figure #2) - On jointly used poles, down guys that pass within 12 inches of supplyconductors, and also pass within 12 inches of communication cables, shall be insulatedwith a guy insulator at a point below the lowest supply conductor and above the highestcommunication cable. (NESC 235I)Guideline 4 (see figure #1) - All guy insulators shall be located at least 8 feet above the groundincluding when the guy would sag or break.

Guideline 5 (see figure #1) - Guy insulators shall be placed so that in case any guy wire contacts, oris contacted by an energized conductor or part, the voltage will not be transferred toother facilities on the structure. (NESC 215C5b)Guideline 6 (see figure #3) - Guys may sag or break, bringing them into contact with energizedconductors, jumpers, or bushings to create a hazard to the public. Guy insulatorsshall be placed so that when any guy sags down or falls upon another facility, theinsulators will remain effective.

5. AnchorsAnchors shall be located so as to provide as large a lead over height ratio with as little interference to the publicas possible.ANCHOR SELECTION1.Anchor Selection in Generala. Anchor selection is based upon guy tension, type of soil, available installation equipment and location.b. Power installed screw anchors are the best choice if soil and location permit their use.c. A plate anchor may be used if a hole can be dug either by machine or blasting or hand dug at inaccessiblelocations.d. If solid rock is encountered, specify one of the rock anchors.e. Some swamp areas cannot be covered by these anchors and must have special design consideration.2. Soil ClassificationThe table of soil classification data which follows is for general use in specifying anchors.Rev 2: Added definitions and updated to 2007 NESC.CONSTRUCTION STANDARDSREVISIONSDATE ENGR OPSR12/22/00JEH22/24/11CMAHGUY & ANCHOR SELECTIONPAGE:6of7GCAD FILE:APP:GDATE:GGWSECTION4/1/86700
CONVERTING HYDRAULIC PRESSURE TO TORQUEIf a shear pin torque indicator is not going to be used, the operator can make a conversion chart so that poundsper square inch of system hydraulic pressure can be converted to torque at the anchor. This chart can be madeby temporarily using a shear pin torque indicator and recording maximum hydraulic pressure readings whenvarious numbers of pins shear. Each pin is equal to 500 ft-lb of torque. After the conversion chart is completed,it is not necessary to use the shear pin torque indicator. Any changes in the hydraulic motor system will requirea new conversion chart. Check the accuracy of the chart annually, after any hydraulic system repairs, or beforecritical anchor installation such as mainline, distribution lines, or transmission lines.Rev 2: Added definitions and updated to 2007 NESC.CONSTRUCTION STANDARDSREVISIONSDATE ENGR OPSR12/22/00JEH22/24/11CMAHGUY & ANCHOR SELECTIONPAGE:7of7GCAD FILE:APP:GDATE:GGWSECTION4/1/86700
