The APDCL Engineer if considered necessary shall make alterations, which shall be carried out accordingly and the APDCL after inspecting the surveyed route and the revised route map shall be given for final approval in writing. The contractor shall not commence the work until the final approval of the route map is given by the Engineer in charge in writing to the contractor.

4. WAY LEAVES AND TREE CUTTINGS: Proposals for way leaves and right of way shall be submitted by the contractor. Permission will be obtained by the APDCL within reasonable time for which due notice shall be given by the Contractor. The Contractor shall arrange for tree cutting or tree branches cutting also. The widths of tree clearance to be adopted for lines of various voltages are that all growth within 6.096 M (20 ft) from the centre line of support and all trees which may fall and foul the line. The Contractor shall take all possible steps to see that standing crops, etc. are not damaged while attending to tree cutting. When such damage is inevitable the compensation will be borne by the APDCL provided the damage is with the prior concurrence of the Engineer. The Contractor shall bear the compensation for damage caused by the gangs without prior concurrence of the Engineer concerned. No trees shall be cut until the APDCL has made necessary arrangement with the authorities concerned and permission is given to the Contractor to fell such trees. The contractor shall arrange to remove the obstacles as soon as possible. At such times, when it may not possible for APDCL to arrange right-of-way for excavation of pole pits or erecting the poles of stringing the line, then at all such times, the contractor shall shift his gangs to other areas. The rates quoted shall cover all such contingencies and no extra payments shall be claimed for such contingencies.

5. EXCAVATION OF POLE PITS, STAY PITS AND D.P. PITS: After the final survey of the line and after

marking the pole locations with pegs, excavation work has to be commenced in accordance to the approved route map. Excavation is generally done by pick axes, crow V-bars and showers although sometimes earth augers are used. Excavation of pole pits in very hard or rocky soil or in rock beds, may involve blasting with suitable explosives. The pits for the supports are excavated in the direction of the line as this will facilitate the erection of support are excavated in the direction of the line as this will facilitate the erection of support, in addition to giving greater lateral stability, the depth of the foundation to be excavated for poles shall be in accordance with relevant sketch for the erection of pole or stay of D.P. etc.

6. ERECTION OF SUPPORTS: After the excavation of pits is completed the supports to be erected may be brought to the pits location. Then the pole may be erected inside the pit. Wooden support may be utilized to facilitate lifting of the pole at the pit locations. Before the pole is put into pit, RCC padding may be laid below the pole to increase the surface contact between the pole and the soil. The padding will distribute the weight of the pole uniformly on the soil. Having lifted the pole, the same should be kept in a vertical position with the help of manila rope of 25 mm dia using the rope as a temporary anchor. As the poles are being erected say from the pole already erected to the next location where the pole is being erected, the alignment of the poles are to be checked and set right by visual check. The verticality’s of the poles are to be checked with a spirit level on both transverse and longitudinal directions. Having satisfied that the verticality and alignment are all right, earth filling or

51 | P a g e

concreting is to be done. In swampy and special locations, however, before earth filing, the poles are to be concreted up to ground level of the pit. After the poles have been set the temporary anchors are to be removed. The supports shall be buried to a depth as per sketch enclosed.

7. ERECTION OF D.P. STRUCTURES FOR ANGLE LOCATIONS (FOR 33 KV LINE): Generally, for

angles of deviation more than 20° double pole structures of spacing 1.2 mts (4.0 ft) may be erected. The pits are to be excavated as per bisection of the angle of deviation. After the poles are erected, the horizontal / cross bracing should be fitted and the supports held in a vertical position with the help of temporary guys of manila rope of at least 25 mm dia. Ensuring that the poles are held in a vertical position (this can be checked with a spirit level) the concreting of the poles with cement, granite chips of size 20/30 mm mesh and sand in the ratio M400 conforming to ISS is to be done from the bottom of the support to the ground level. Before lifting the pole in the pit, concrete padding of not less than 75 mm thickness may be put for the distribution of the load of the support on the soil. After the concreting is done, the pit may be filled with earth after curing of the concrete is completed. Four stays along the line, two in each direction and two stays along the bisection of angle of deviation are to be provided. Stay concreting may be done with M 400 concrete mixture. The D.P. shall be erected as per the sketch enclosed.

8. ANCHORING AND PROVIDING GUYS FOR SUPPORTS: Guys are to be provided to the supports at

the following places (i) Angle locations, (ii) Dead end locations, (iii) Tee-off points, (iv) Steep gradient locations to avoid uplifted on the poles. The installation of guy will involve the following works:

i. Excavation of pit and fixing of stay rod. ii. Fastening guy wire to the support. iii. Tightening guy wire and fastening to the anchor

The marking of the guy pit for excavation, the excavation of pits and setting of the anchor rod must be carefully carried out. The stay rod should be placed in the position such that the angle of inclination of the rod with the vertical face of the point is 30°/45° as the case may be. The concreting of the stay at the bottom should then be carried out. The back filling and ramming must be well done thereafter, and allowed to set for at least 7 days. The free end of the guy wire is passed through the eye of the anchor rod, bent back parallel to the main portion of the guy and bound after inserting the G.I. Thimble. The loop is protected by the G.I. Thimble, where it bears on the anchor rod. Where the existence of guy wire proves hazardous, it should be protected with suitable asbestos pipe, filled with concrete of about 2 mts length above the ground level, duly painted with white and black stripe so that it may be visible at night. The turn buckle shall be mounted at the pole end of the stay and guy wire so fixed that the eye bolt turn buckle is half way in the working position, thus giving the maximum movement for tightening or loosening. Guy insulators are placed to prevent the lower part of the guy from becoming electrically energized by a contact of the guy when the conductors snap and fall on them of due leakage. No guy insulator shall be located less than 2.6 mts. from the ground. The anchoring and providing guys for supports (Single guy Bow guy fly guy) shall be done as per sketch enclosed. Bow guy and fly guy shall be provided as per field conditions. 9. FIXING OF CROSS ARMS INSULATORS: After the erection of supports and providing guys, the next

step would be to mount the cross arms on the support erected. The lineman should climb the support having requisite tools with him and the cross arm is then tied to a hand line and pulled up by the ground man and should station himself well to one side so that if any material drops from the top of the pole it may not strike him. All the materials required should be lifted or lowered by means of the hand line. In no case, the materials of the tools should be dropped or thrown from the pole top. The fixing of 33 KV, 11 KV and LT Cross arms shall be in accordance to spacing detailed in Sketch. G.I. bolts and nuts and spring washers of good quality only shall be used which will have to be procured by the contractor.

a. Back Clamps; The back clamps for fixing of the seating channels, “V” cross arms, horizontal cross arms and top cleats will have to be procured by the contractor and shall be in accordance with sketch enclosed and the clamp shall be fabricated with 75 X 8 mm G.I. Flat for 33 KV and 50 X 8 mm G.I Flat for 11 KV.

b. Top Cleats The top cleats shall be got fabricated with G.I. Channel of size 100 X 50 mm for 33 KV and 11 KV and shall be in accordance with sketch enclosed.

10. INSULATORS: The pins for insulators shall be fixed in the holes provided in the cross arms and the pole top brackets. The insulators shall be mounted in their places over pins and tightened. In the case of strain or angles supports, where strain fittings are provided for this purpose, one strap of the strain

52 | P a g e

fitting is placed over the cross arm before placing the bolts in the hole of the cross arms. The nut of the strap is so tightened that the strap can move freely in horizontal direction, as this is necessary to fix the strain insulator. The insulator shall be cleaned and examined for defects before fixing, it shall be ensured that all the current carrying parts are smooth and without dirt, cracks or chips.

11. STRINGING OF THE LINE CONDUCTORS For the guidance of the contractor certain do’s and don’ts are given below before the workmen actually commence the stringing work a. Do’s and Don’ts

DO’s i. Use proper equipment for handling aluminum conductors at all times. ii. Use skids, or similar method for lowering reels or coils from transport or ground. iii. Examine reel before unreeling for presence of nails or any other object, which might

damage the conductor. iv. Rotate the reel or coil while unwinding conductor. v. Grip all strands while pulling out the conductor. vi. Control the unreeling speed with suitable braking arrangement. vii. Use wooden guards of suitable braking arrangement. viii. Use long straight, parallel jaw grip with suitable liners when pulling conductor thus

avoiding nicking or kinking of the conductor. ix. Use free running sleeves or blocks with adequate grooves for drawing/paving

conductors. x. Use proper sag charts. xi. Mark conductors with crayons or adhesive tape of such (other) material, which will not

damage the strand. xii. Make all splicing with the proper tools. xiii. Use a twisting wrench for twisting the joints. xiv. Chromite or graphite conducting oxide-inhibiting grease should be used before cleaning

with wire brush. DON’Ts

i. Do not handle conductors without proper tools at any stage. ii. Do not pull conductors without ensuring that there are no obstructions on the ground. iii. Do not pull out excess quantity of conductor than is required. iv. Do not make jumper connections on dirty or weathered conductor. v. Do not handle aluminium conductors in a rough fashion but handle it with care it

deserves. b. CONDUCTOR ERECTIONS: The erection of overhead line conductor is a very important phase in

construction. The erection of conductors can be sub-divided into 4 separate parts as follows: i. Transport of conductors to work site. ii. Paving and stringing of conductors. iii. Tensioning and sagging of conductors. iv. Joining of conductors.

At the important crossing of roads, canals, navigable rivers, railways etc., flagmen should be in attendance to ensure that normal services are not unduly interrupted. These crossing should only be carried out in conjunction with and with the approval of the proper authorities concerned. The conductor drums shall be transported to the tension point without injuring the conductor, if, it is necessary to roll the drum on the ground for a small distance, it should be slowly rolled in the direction of the marked on the drum. The drum should be so supported that it can be rotated freely. For this purpose the drum should either be mounted on the cable drum supports of jacks or hung by means of chain pulley of suitable capacity, suspended from a tripod. In case if it is not possible to raise the conductor drum by any of the above method, a trench of suitable depth slightly bigger than the conductor drum may be dug, so as to facilitate free rotation of the cable drum when it is suspended in the trench by means of M.S. Shaft. While paving, care should be taken to see that conductor does not rub against any metallic fitting of the pole or on the bad/rocky ground. Wooden trusses should be used for this purpose to support the conductor. The conductor should be passed over the poles on wooden or aluminium snatch pulley blocks provided with low friction bearings. While conductor is being paved out slowly, some braking arrangement should be made so that the rotation of the drum may be stopped in emergency. In case the length of one piece of the conductor is less than the length of the section in which conductor paving is being done, it is easy to stretch one length of all phases from one end the remaining length from another end of the section any part

53 | P a g e

of the conductor shall be left at a height of less than that of 5 meters, above the ground by rough sagging.

c. MID SPAN JOINTING OF CONDUCTORS

The mid span jointing of conductors can be carried by twisting the joint at the ends and the wire should project a few centimetre, beyond the end of the sleeves. The projected wires are given a sharp bend to keep them from slipping out of the sleeve. The end of the sleeves are then held tightly by twisting wrenches and then 4 to 5 turns in one direction generally anti-clock wise direction. Crimping Tools are preferably to be used for joints and jumpers.

d. SAGGING AND TENSIONING

On the completion of the paving of the conductors and making mid span joints if any, tensioning operations will commence. Temporary guys will have to be provided for both the anchoring supports in the section where the stringing has to be done. At the tensioning end, one of the conductors is pulled manually up to a certain point and then come along clamp is fixed to the conductor to be tensioned. The grip to the come along clamp is attached to double sleeve pulley block or the pulley lift machine and gradually tensioned. The conductor should then be sagged in accordance with the sag temperature chart for the particular conductor and span. The sag should then be adjusted in the middle span of the section. The sag chart is to be provided. The stretch of the conductor has to be taken out before stringing in order to avoid the gradual increase in sag due to the setting down of the individual wires. There are ways of accomplishing this:

e. PRE-STRESSING In this method the conductor is pulled up to tension considerably above the correct figures, but never exceeding 50% of breaking load for a short period of say twenty minutes. As this method requires more time and involves the use of stronger tackle to secure the higher tension the other method of over tensioning is commonly adopted.

f. OVER-TENSIONING This method consists of pulling up the conductor to a tension a little above the theoretical tension for prevailing temperature and fixed it up at that tension with correspondingly reduced sag. After a certain time the conductor will settle down to the correct sag and tension. A tension of five to eight percent more than the theoretical value has been found to be suitable for the sizes of ACSR and AAAC conductors standardized by REC. The ambient temperature during sagging may be recorded correctly. Conductors can be sagged correctly only when the tension is the same in each span throughout the entire length of section. Use of snatch blocks reduces the friction and chances of inequality of tension in various spans. Sagging can be accomplished by several different methods but most commonly used method is “Slighting”. The slighting sag method of measuring sag is by the use of targets placed on the supports below the cross arms. The targets may be light strip of wood clamped to the pole at a distance equal to the sag below the conductor when the conductor is placed in snatch block. The lineman sees the sag from the next pole. The tension of the conductor is then reduced or increased, until the lowest part of the conductor in the span coincides with the lineman’s line of sight. When sagging is completed, the tension clamps shall be fixed. The clamp can be fitted on the conductor without releasing the tension. A mark is made on the conductor at a distance from the cross-arm equal to the length of complete strain insulator. Before the insulator set is raised to position, all nuts should be free. Come along clamp is placed on the conductor beyond the conductor clamp and attached to the pulling unit. The conductor is pulled in sufficiently to allow the insulator assembly to be fitted to the clamp. After the conductor is clamped to insulator, assembly unit may be released gradually. If the tension is released with a jerk, an abnormal stress may be transferred to conductor and support, which may result in the failure of the cross arm, stay or pole in some cases. After the stringing is completed, all poles, cross arms, insulators, fittings etc. are checked upto ensure that The next step is to place the conductor on the top of the pin insulator from the snatch block and removing snatch blocks. Conductors are then fastened to insulator by the use of aluminium wires. The following points should be observed:

i. Proper size of the tie binding wire which can be readily handled and with adequate strength is to be used.

ii. The length of tie wire should be sufficiently long for making complete tie including the end allowances for gripping with ends.

iii. A good tie should provide a secure binding between the line conductor and insulator and should reinforce the conductor on either side of the insulator.

iv. The use of cutting pliers for binding the tie wire should be avoided.

54 | P a g e

v. The tie wire which has been used previously should be reused Before tying the conductor to the insulator two layers of Aluminium tapes should be wrapped over the conductor in the portion where it touches the insulator. The width and thickness of aluminium tape to be used for a specific size of conductors has been specified in hand books of Aluminium conductor manufacturers and the same be referred to. The Aluminium tapes should also be used at the tension clamp and for proper grip. Normally in straight runs of line, the conductors are run on the top of insulators. When there is small of deviation the conductor is placed inside groove and bound. Accordingly, there are two methods of tying the conductors to insulators. The binding wire/tie wire has to be procured by the contractor and the bid price shall include the cost of this.

g. The contractor shall be entirely responsible for any damage to the supports, other accessories and conductor. He shall also be responsible for proper distribution of the conductor drums to keep number and lengths of cut pieces of the conductor to a minimum.

h. CONDUCTOR DAMAGE AND REPAIR: If the conductor is damaged for whatever reasons, and damage is not repaired by aluminium sleeves, etc., it shall be brought to the notice of the Engineer and shall not be used without his approval. Even repairing of conductor surfaces shall be done only in case of minor damages, scuff marks etc., which are safe from both electrical and mechanical points of view. The final; conductor surface shall be clean, smooth, without any projection sharp points, cut or abrasion etc. giving satisfactory corona and R.I. performance.

i. No joints or splice be made in span’s crossing over main roads, railways, small rivers or intension spans. Not more than one joint per conductor shall be allowed in one span. The strength of the joint shall conform to IE Rule 75.

Wooden support may be utilized to facilitate lifting of the pole at the pit locations. Before the pole is put into pit, RCC padding may be laid below the pole to increase the surface contact between the pole and the soil. The padding will distribute the weight of the pole uniformly on the soil. Having lifted the pole, the same should be kept in a vertical position with the help of manila rope of 25 mm dia using the rope as a temporary anchor. As the poles are being erected say from the pole already erected to the next location where the pole is being erected, the alignment of the poles are to be checked and set right by visual check. The verticality’s of the poles are to be checked with a spirit level on both transverse and longitudinal directions. Having satisfied that the verticality and alignment are all right, earth filling or concreting is to be done. In swampy and special locations, however, before earth filing, the poles are to be concreted up to ground level of the pit. After the poles have been set the temporary anchors are to be removed. The supports shall be buried to a depth as per REC construction standard.
