shall be claimed for such contingencies.

1.3 EXCAVATION OF POLE PITS, STAY PITS AND D.P. PITS

a. 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.

1.4 ERECTION OF POLES :

a. G.I. STEEL TUBULAR POLE :

STEEL TUBULAR poles should be erected perpendicular to ground level including excavation of

earth pit having depth equal to 1/5 th the length of pole and cross-section 75 cm x 50 cm as

directed by department including dragging and carrying of pole to site as per soil condition as

given below.

(i) earth filling with soil at bottom and surrounding with vigorous ramming;

(ii) earth filling with soil at bottom and surrounding with vigorous with boulder packing including

supply of boulder by contractor ( size of boulder 150mm x 200mm);

(iii) grouting and mufflering in proportion 1:2:4 RCC foundation and filling of cement concrete as

per specification including supply of cement , stone chips, shuttering etc. as directed ]

b. POLE CLAMP:

The pole clamp is to be made of MS flat of size 40 mm x 6 mm with necessary drilling of holes

and painting with primer and anti corrosive paint suitable for different size of steel tubular pole

and PSC pole.

1.5 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 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.

1.6 ERECTION OF D.P. STRUCTURES FOR ANGLE LOCATIONS (FOR 33 LINES) 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 approved drawing.

1.7 ANCHORING AND PROVIDING GUYS FOR SUPPORTS

Fitting of stay set on overhead line including digging of earth pit of area 90cm x 60 cm and depth of

1.4 m placing the stay rod with G.I stay wire Guy insulator on pole clamp , fixing of thimble bow etc

with hard soil packing and ramming to fill up pit to ground level.

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.

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 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

2.2 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 aluminum 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 aluminum 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 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 centimeter, 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:

i. 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.

ii. 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

there have been no deformities etc.


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 aluminum 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.

v) The tie wire which has been used previously should be reused

Before tying the conductor to the insulator two layers of Aluminum tapes should be wrapped over

the conductor in the portion where it touches the insulator. The width and thickness of aluminum

tape to be used for a specific size of conductors has been specified in hand books of aluminum

conductor manufacturers and the same be referred to. The Aluminum 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.

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.

e. Conductor damage and repair

If the conductor is damaged for whatever reasons, and damage is not repaired by aluminum

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.

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.

f. Stringing.

Whatever necessary ground clearances have to be measured to ensure obtaining adequate line

clearance as per IE Rule 77 (i)

GUARDING :

When an overhead line crosses or is in proximity of any telecommunication line arrangement

shall be made to provide protective device or guarding.
