5 CONFIGURATIONS Structural Elements Design Limits 3 3 Sheet 1 of General This standard gives the design limits of the structural elements employed in building standard configurations. These limits are based on the allowable loading of crossarms and pins as shown in Dist. Std. 29 4, and also on required conductor separation to prevent midspan conductor contact. 2. Angle Limits Tables 1, 2, 3, 4 and 5 specify the maximum angle capable of being turned on pins, insulators, fiberglass standoffs, combination fiberglass and porcelain standoffs, and crossarms for various types of construction. This data is based on the transverse strength of the components of the structure and the load applied to it, due to the line angles. 3. Dead End Loadings Table 6 specifies the maximum balanced dead end loading for unguyed crossarms. It shows the number of conductors permitted to dead end on a structure, depending on the size of conductor and the type of dead end structure. The data is based on standard conductor tensions and allowable equivalent horizontal loadings on the crossarm. The purpose of this table is to provide the information necessary to get the most out of a dead end structure without having to resort to crossarm guying.

Maximum number of pins for single crossarm is 2. Maximum number of pins for double crossarm without grid plate is 4; and maximum number of pins for double crossarm with grid plate is 6. The number of conductors that can be deadended back to back (not on pins) is only limited by the strength of the joint between the arm(s) and the pole. 2. Above table based on Grade N construction.

Select The Required Crossarm Assembly Unit Using The Following As A Guide 1. The above table, based on maximum span length of applicable sag table, automatically takes care of vertical loadings. For shorter span lengths the crossarm may be strong enough; however, a strength calculation should be made. See Dist. Std for examples and allowable crossarm loads. 2. Inadequate vertical strength for the number and size of conductors shown. 3. Double arms and double dead end pole top construction shall always be used. a. At all railroad crossings. Note: If tensions do not exceed 2 lbs. per conductor during heavy loading; double pins and ties may be used. Double pole top pins mounted on the face of the pole may be used to meet this requirements. (Tensions for conductors sagged in accordance with Sag Table 1 does not exceed 2 lbs. under heavy loaded conditions except for kcmil A.A. and 795 kcmil A.A.). b. On grade B circuits where the line angle exceeds 2 o. c. On grade B circuits at communications crossings, if the supply conductors are not continuous and of uniform tension in the crossing span and each adjacent span. 4. Angles shown for single or double pins refer to crossarm pins and existing pole top pins mounted on the face of the pole. 5. Grid gain plates (Dist. Std. 4 35) shall be used only when required for the larger angles shown. Use caution to insure that pin angle limits are not exceeded (2 or 3 conductors). If pin limits are exceeded, use double dead ends. 6. Above table based on grade N construction. ENG: DCG REV. NO: 7 REV. DATE: 2/21/12

138 GUYING General Sheet 1 of 3 1. GENERAL Guys are used to sustain unbalanced forces imposed on a structure at corners, angles, deadends, large differences in span lengths, and changes of grade of construction. Guys shall be considered as taking the entire load in the direction in which they act, with the pole or structure acting as a strut only, resisting the vertical component of all forces. The strength requirements of guy and anchor systems are governed by the National Electric Safety Code which specifies criteria for calculating conductor tensions and imposes overload factors to be used under different circumstances. Guying is preferable to oversized self sustained poles. Where adequate guying cannot be obtained due to right of way or other difficulties, self sustained poles, within their limitations, may be used. Loadings and other details for self sustained poles are covered in Dist. Stds thru GUY WIRE & FITTINGS Three sizes and grades of galvanized steel guy wire are stocked for normal use. The maximum tension and associated fittings for each guy wire is given below in Table 1. The maximum tensions shown are 9 percent of the rated breaking strength, in accordance with the NESC. In Illinois, 1/4 guy wire is not used. GUY WIRE TABLE 1 PREFORMED GRIP AUTOMATIC DEADEND Stock No. Size & Grade Max. Tension (lbs) Stock No. Stock No /4 Galv. E.H.S 5, /8 Galv. E.H.S. 13, /16 Galv. E.H.S. 18, In general, all guy strand shall be secured to the pole fitting or to guy insulators with preformed guy grips. Automatic Deadends may only be used with galvanized guy wire at the anchor or guy pole. Due to increased cost, there is no need for more than one automatic installed per guy lead. 3. ANCHORS & ANCHOR RODS Three types of anchors are available for use in the distribution system; power installed screw anchors, expanding anchors and rock anchors. 3.1 Power installed screw anchors are the preferred anchors for use in all soils other than solid rock. Access with a power digger equipped with wrench assembly is required for installation. Two strengths of these anchors are stocked; a 6, ft lb series for use in sandy to hard pan soils, and a 1, ft lb series for use in rockier soils in which the 6, ft lb anchors cannot be installed. Only square shaft anchors shall be used in Illinois for down guys on Sub Transmission (34.5kV and 69kV). 3.2 Expanding anchors can be installed in most any soil in which an 8 to 12 diameter hole, depending on anchor size, can be augered. Because of the time needed to install these anchors, usage is generally limited to locations not accessible to power equipment. ENG: DG REV. NO: 8 REV. DATE: 8/12/15

139 GUYING General Sheet 2 of Rock anchors are an expanding type anchor which must be installed in at least 12 of solid rock. A 2 or 2 1/4 diameter hole is needed for installation. Rod lengths from 3 to 96 are available to meet site requirements. Standard sizes, holding strengths and methods of installation for each type of anchor are shown in Dist. Std ** thru **. 4. USE OF GUY INSULATORS Guy strain insulators are used to: (1) protect pedestrians and line workers if a guy accidentally contacts supply conductors, (2) minimize the possibility of plant damage which may result in unsafe conditions, and (3) increase the structure BIL and reduce lightning caused outages. All guys attached to poles supporting energized conductors or equipment shall have a minimum of one guy strain insulator inserted in each guy. EXCEPTION: Stub pole to anchor guys generally do not require an insulator unless the exposure between the energized pole and the stub pole cannot be isolated. One insulator typically cannot be located to satisfy all of the following requirements. Additional insulators shall be used as required. Where multiple guys are required, the insulators in each guy shall be located so that in case any guy sags down upon another, the insulators will not become ineffective (NESC Rule 215C5C). DCS demonstrates the general concepts of proper guy strain insulator placement described in this DCS. DCS gives more detailed guidance for guy strain insulator placement for many of Ameren s typical structure configurations. If necessary, a fiberglass (FG) guy strain insulator may be used to allow a guy to be located in closer proximity to a conductor than would otherwise be allowed. In no instance, however, shall any conductive portion of the guy or the insulator be located in closer proximity to a conductor than is specified in DCS To achieve the updated requirements from the 212 NESC as described in this DCS, it will often be necessary to link two or more FG guy strain insulators together. 4.1 Distribution In Missouri, FG or porcelain guy strain insulators may be used in guys associated with circuits 15 kv and below. In Illinois, only FG guy strain insulators shall be used. Insulators shall be installed to meet all of the following placement criteria that apply: a) A FG guy strain insulator shall be used at the pole attachment of all anchor or span guys. EXCEPTION: Stub pole to anchor guys do not require insulators if the span guys are effectively isolated and there are no energized conductors or communication attachments on the stub pole. b) On non joint use poles, an insulator (or at least 12 of a FG insulator) must be located between primary voltage and secondary voltage (including neutral) supply circuits. This insulator must be located so that: i. It prevents the possibility of voltage transfer between the primary and secondary circuits during normal operation of the guy, and ii. If the guy wire breaks below the insulator, it will fall below all primary voltage supply conductors and above any secondary conductors (including the neutral) as it rests against the pole. c) On non joint use poles, an insulator (or at least 12 of a FG insulator) must be located between the lowest supply conductor (primary, secondary, or neutral) and ground. The insulator must be located so that: i. It prevents the possibility of voltage transfer between the lowest supply conductor and ground during normal ii. operation of the guy, and If the guy wire breaks below the insulator, the insulator falls below the lowest supply conductor and the bottom of the insulator must fall a minimum of 8 ft. above the ground as it rests against the pole. d) On joint use poles, in addition to a) and b) above an insulator (or at least 12 of a FG insulator) must be located between the lowest supply conductor (primary, secondary, or neutral) and the highest communication cable. This insulator must be located so that: ENG: DG REV. NO: 8 REV. DATE: 8/12/15

140 GUYING General Sheet 3 of 3 i. Any guy passing within twelve inches (12 ) of a supply conductor and also passing within twelve inches (12 ) of a communication cable shall have an insulator located below the lowest supply conductor and above the highest communication cable (NESC Table 235 6, Note (1)). ii. It prevents the possibility of voltage transfer between the supply circuits and communication cable during normal operation of the guy, and iii. If the guy wire breaks below the insulator, it will fall below all supply conductors and above any communication cables as it rests against the pole. e) On joint use poles, an insulator (or at least 12 of a FG insulator) must be located between the lowest communication cable and ground. The insulator must be located so that: i. It prevents the possibility of voltage transfer between the lowest communication cable and ground during ii. normal operation of the guy, and If the guy wire breaks below the insulator, the insulator falls below the lowest communication cable and the bottom of the insulator must fall a minimum of 8 ft. above the ground as it rests against the pole. EXCEPTION: This insulator is not required if the communication cables are self supported fiber optic (with no metallic messenger). 4.2 Sub Transmission Guys associated with 34.5kV or 69kV circuits require a FG guy strain insulator be used in place of a porcelain insulator. In addition to the protective role, FG guy strain insulators serve to increase the BIL level of ungrounded structures associated with these circuits. FG guy strain insulators shall be installed to meet all of the following placement criteria that apply in addition to the criteria in section 4.1 of this DCS: a) A FG guy strain insulator shall be used at the pole attachment of all anchor or span guys. EXCEPTION: Stub pole to anchor guys do not require insulators if the span guys are effectively isolated and there are no energized conductors on the stub pole. b) If no underbuilt circuits are present, at least 24 of a FG insulator must be located between the lowest 34.5kV or 69 kv conductor and ground. The insulator must be located so that: i. It prevents the possibility of voltage transfer between the lowest supply conductor and ground during normal operation of the guy, and ii. If the guy wire breaks below the insulator, the insulator falls below the lowest supply conductor and the bottom of the insulator must fall a minimum of 8 ft. above the ground as it rests against the pole. c) If an underbuilt circuit is present, at least 24 of a FG insulator shall be located to effectively isolate the lowest 34.5kV or 69kV conductor and the highest distribution underbuilt conductor. 4.3 Span Guys All of the requirements of sections 4.1 and 4.2 of this DCS also apply to span guys. 5. GUY MARKERS Guy MARKERS shall be installed on the ground end of all anchor guys. Where two or more guys are attached to the same anchor, only one MARKER is required and shall be installed on the highest guy wire. ENG: DG REV. NO: 8 REV. DATE: 8/12/15

155 LIGHTNING PROTECTION AND GROUNDING General Sheet 1 of 8 1. General This section outlines standard ratings of lightning protective equipment, methods of installation, equipment to be grounded, and methods of grounding. 2. Lightning Protection Two types of lightning protective equipment are used to protect OH lines and associated equipment. These are Overhead Static Wire and Lightning Arresters. 2.1 Overhead Static Wire This is a grounded overhead wire installed above the circuit to be protected to shield it from lightning. It is located at an elevation such that a line passing through the static wire and the outermost conductor below it is at a 3 O maximum angle with a vertical line. This continuous overhead static wire is grounded by means of a formed copper wire grounding electrode at each pole Installation of Static Wire The preferred method of lightning protection of overhead sub transmission circuits is through use of an overhead static wire. The static wire shall be grounded at every pole except manually operated group air break switch poles. The best protection is afforded by low pole ground resistance (less than 15 ohms). Existing circuits which qualify for improved lightning protection shall be protected in this manner. Additional pole height may be required to add a static wire. A fiberglass pole top extension or a wood bayonet can be used for added height. 2.2 Lightning Arresters Metal Oxide Varistor (MOV) arresters are normally used for protection of overhead distribution circuits or equipment where conditions warrant (e.g. high ground resistance or retrofitting shielded circuits with a poor history of lightning performance). These arresters (mostly zinc oxide) are solid state and are direct connected from line to ground. MOV arresters are sensitive to temporary system overvoltage such as may occur due to ferroresonance or to single phase switching of ungrounded wye delta transformer banks. In such instances contact Standards engineering for recommendations. Higher voltage arresters may be required. There are many silicon carbide internally and externally gaped arresters still on the system. These allow a higher discharge voltage than MOV arresters, reducing the surge protective margin. When these are found during work on a pole they should be replaced with a polymer housed metal oxide (MOV) arrester (especially at riser poles) Installation of Lightning Arresters When installed to protect equipment, arresters shall be installed as near as practical to the equipment to be protected. See Table 2 for equipment to be protected. ENG:WYW REV. NO: 21 REV. DATE: 11/18/16

156 LIGHTNING PROTECTION AND GROUNDING General Sheet 2 of 8 Arresters are also installed on sub transmission for general line protection. In this application, arresters should be installed on the top phase of every pole where a 3 O shield angle exists. Skipping spans severely reduces the ability of the arresters to protect against direct stroke flashovers. Where lines run through wooded areas or close (within 1 1/2 pole heights) to any type of structure at least as tall as the top phase, induce flashovers may be experienced. If outages are experienced in this circumstance, arresters should be installed on the remaining phases of the circuit(s) at roughly 6 intervals. Where a shield angle greater than 3 O exists, arresters should be placed on all three phases of every pole in open territory. Where the line runs through areas shielded by trees of other structures, arresters should be installed on all three phases at roughly 6 intervals. Distribution underbuild, particularly when built with all three phases on one crossarm, will many times experience flashovers from the ground lead of either static construction or arresters on the sub transmission circuit(s). If experience indicates this to be the case, arresters should be installed on the B phase (closest to the pole). In all cases the primary connection lead as well as the ground lead should be as short as possible and free of any sharp bends. Under no circumstances should pigtail coils be made in the arrester connecting leads. Installation notes: 1. Connect the arrester ground lead before connecting the arrester to the line. 2. Install wildlife guards on line terminals of all line arresters and cover (stk # ) over transformer sidewall bracket arrester attachment bolt. 3. Do not reconnect arresters with a blown ground lead disonnector. 4. Arresters removed for any reason shall not be re installed. ENG:WYW REV. NO: 21 REV. DATE: 11/18/16

159 LIGHTNING PROTECTION AND GROUNDING General Sheet 5 of 8 Per NESC code, multiple ground leads on the same pole shall be bonded together. Ground rods will continue to be used for grounding pad mounted equipment and existing pole ground installations. For new pole ground installations a formed #2 soft drawn copper electrode shall be used. This electrode is to be placed at the bottom of the pole and covered with at least six inches of native soil. The vertical lead of the electrode should be trained to the side of the pole hole so that it will not be covered by the crushed rock backfill. If the desired resistance is not obtained additional ground rods can be driven in parallel with the formed electrode but a minimum separation distance of six feet shall be maintained. 3.2 The Common Neutral System Either a 24/416 Y volt or a 72/1247 Y volt common neutral distribution system is normally used at Ameren. These systems use a continuous metallic conductor which serves as both the primary and secondary neutral conductor. This neutral conductor must be attached to grounds at various points throughout its length to insure adequate grounding of the circuit. These grounds (Table 3) will consist of customers grounds, lightning arrester grounds, and static wire grounds and occasionally a ground installed solely to provide adequate grounding of the common neutral. Where a common neutral is present, all grounds installed for any purpose shall be bonded to it. 3.3 Number of Grounds Common Neutral At least four grounds are required, (counting equipment grounds but not counting customers grounds), in each mile of common neutral circuit for both overhead and underground circuits (maximum 132 feet spacing). In cases of random lay underground with other utilities, at least 8 grounds per mile are required. Where it is necessary to install additional grounds because of this requirement, approximately uniform spacing shall be used. See Table Size of Ground Wire The size of ground wire will vary according to the type of equipment being grounded and shall conform to Table 3. In areas of frequent damage/vandalism, 7#1 copperweld should be substituted for the #6 soft drawn copper pole ground wire. ENG:WYW REV. NO: 21 REV. DATE: 11/18/16

161 LIGHTNING PROTECTION AND GROUNDING General Sheet 7 of 8 NOTES: 1 Pole line hardware (including cluster bracket and streetlight brackets) must not be grounded except with engineering approval. 2 Where a lightning arrester is installed on a secondary or service the arrester ground lead shall be solidly connected to any one or combination of the following grounds: a The neutral or grounded service wire. b Customer s common grounding conductor. c Customer s equipment grounding conductor. da. A separate grounding conductor such as a driven rod. 3.6 Ground Wire Attachment and Covering The ground wire shall be run in a straight line or a smooth curve and shall clear hardware by at least 2 inches. The static ground wire from 34kV circuits shall be routed on the opposite side of the pole away from the closest phase of any underbuilt circuit. Avoid making sharp bends in ground wires. Take care when driving staples onto ground wires to avoid damaging the wire. Where the ground wire passes over a messenger or guy wire, a loop shall be formed to clear the messenger or guy wire. If necessary a bridge shall be made from a 6 length of plastic molding, placing the half round of the molding against the pole and taping the ground wire in place in the groove. Where guarding is not required, grounds shall be protected by being substantially attached closely to the surface of the pole or other structure in areas of exposure to mechanical damage and, where practical, on the portion of the structure having least exposure. A 4 section of molding may be placed over the ground wire in the working area on badly congested poles. The purpose of the molding is to keep linemen s climbers from damaging the ground wire when working on primary circuits. Ground wire molding is required for installations with no common neutral and separate arrester/equipment tank and secondary neutral grounds. These separate grounds shall be made with 6 volt insulated conductor (use stk # ) and shall be covered with plastic molding for a distance of 8 feet from the ground. The arrester/tank ground and secondary ground can be connected using an isolation arrester (stk #1 1 19). One ground wire can be connected to a driven ground or coiled ground electrode at the base of the pole but the other ground wire shall be carried (buried) to a driven ground rod at least 2 feet from the base of the pole and connected with #2 SD bare copper conductor. 3.7 Static Wire at Substation 1/ AAC or 12/7 ACSR static wire shall be electrically continuous and tied into the bulk substation ground grid. Where the connection into the substation cannot be made overhead, direct bury a 4/ bare copper conductor from the last pole with static termination to the substation ground grid. The 4/ size conductor allows ENG:WYW REV. NO: 21 REV. DATE: 11/18/16

162 LIGHTNING PROTECTION AND GROUNDING General Sheet 8 of 8 some safety margin for corrosion. The downlead from the static wire to the 4/ conductor shall be #2 copper. 3.8 Static Wire Personal Protective Grounds a Wire Common Neutral 1/ AAC or 11.8 (12/7) ACSR (or other shield wires having current capacity of 25 amps or greater) may be used for direct connection of protective grounds on 35 and 69 kv circuits if there is a common neutral and 7#1 CW pole grounds (or other pole grounds with current capacity of at least 5 amps) connected to the shield wire for at least two poles in each direction. The common neutral must also be connected to the down leads at each pole. b Without Common Neutral 1/ AAC or 11.8 (12/7) ACSR (or other shield wires having current capacity of 25 amps or greater) may be used for direct connection of protective grounds on 35 and 69 kv circuits with no common neutral present if #2 copper down leads are grounded at every 4 th pole (no more than 12 feet apart); a supplementary grounded rod must be driven at least 6 feet from the closest ground rod. This extra ground rod shall be connected with #2 copper to the #2 copper down lead.. Alumoweld Static Wire Alumoweld static wires have been installed in the past. Do not connect protective grounds to Alumoweld. It may fuse if a fault occurs. To improve protective grounding on 35 kv lines with Alumoweld static and poor ground resistance, #2 copper downleads may be installed at intervals of 4 spans (no more than 12 feet). Protective grounds can then be connected to the #2 Cu. A supplemental ground is required from #2 copper downlead to a second driven ground. 3.9 Static Wire/Common Neutral System 1/ AAC or 11.8 (12/7) ACSR (or other static wires having current capacity of 25 amps or greater)may be used as the common neutral for lower voltage underbuilt circuits where the run is 3 feet or more. In such cases the static wire must be continuous and connected to the source transformer neutral with #2 SD poly covered wire. The static wire shall not be used in place of the secondary neutral. Where secondary is present the secondary neutral shall be paralleled with the static wire neutral and interconnected at every static wire ground down lead. However, where this would result in short discontinuous sections of neutral a continuous neutral shall be installed from the source transformer. To equalize ground potential static wire ground leads, arrester ground leads, neutral ground leads and equipment case ground leads shall be bonded together with the only exceptions noted in the transformer section of these standards.
