Indian Standard SPECIFICATION FOR
TUBULAR STEEL POLES FOR OVERHEAD POWER LINES
(Second Revision )
0. FOREWORD
0.1 This Indian Standard (Second Revision) was adopted by the Indian Standards Institution on 30 September 1980, after the draft finalized by the Structural Sections Sectional Committee had been approved by the Structural and Metals Division Council.
0.2 This standard was first published in 1964 and was revised in 1969. In this second revision besides incorporating the Amendments No. 1 and 2, the following modifications have been effected:
a) The standard had earlier covered poles made of high strength steel only (tensile strength 540 MPa or 55 kgf/mm2). In this revision poles made of mild steel (tensile strength 410 MPa or 42 kgf/mm2) have also been introduced.
b) The range of pole sizes has been enlarged.
1 MPa = 0.101 972 kgf/mm*.
The strength of poles the minimum values strength of steel.
has been based on of ultimate tensile
Reference has been made to IS : 1161-1979* for tubes used to make poles. Use of manual metal arc welding process has also been permitted for making tubes.
SI units of measurement have been used.
0.3 This standard has been prepared in three parts as follows for convenient usage:
Part I General requirements
Part II Special requirements for poles made from steel of tensile strength 410 MPa
Part III Special requirements for poles made from steel of tensile strength 540 MPa
*Specification for steel tubes for structural purposes (third revision).

Indian Standard SPECIFICATION FOR
TUBULAR STEEL POLES FOR OVERHEAD POWER LINES APART I GENERAL REQUIREMENTS
(Second Revision)
1. SCOPE
1.1 This part covers the general requirements for tubular steel poles of circular cross section for overhead power lines.
1.2 These general requirements apply to tubular steel poles made of steels of minimum tensile strength 410 MPa and 540 MPa which are covered in Part II and III respectively of this standard.
2. TERMINOLOGY
2.0 For the purpose of this standard, the following definitions shall apply.
2.1 Breaking Load - The theoretical load which would produce at ground level a stress equal to the tensile strength in the material. This is only of theoretical interest. In reality, the elastic limit of the material would be exceeded qnd consi- derable deformation would occur before this theoretical load could be applied.
2.2 Load for Permanent Set - The maximum load which may be applied without producing at the gripping and a permanent set higher than specified. The permanent set measured at the point of application of this load shall not exceed 13 mm.
2.3 Load for Temporary Deflection - The maximum load which may be applied without producing at the point of application of this load a temporary deflection exceeding 157.5 mm.
2.4 Crippling ~Load - The load which is just sufficient to cause crippling of the pole.
2.5 Point of Application of Load - For the purpose of definitions from 2.1 to 2.3, the load should be applied at right angles to the axis of the pole at a point 30 cm below the top' for poles of length up to and including 9 m and at a point 60 cm below the top for poles longer than 9 m. The pole should also be considered planted to specified depth.
2.6 Lot - A collection of poles of one designation manufactured by the same process under similar conditions of production and offered for inspection at a time.
2.7 Lot Size - Number of poles in a lot.
3. TYPES

5. MANUFACTURE
5.1 The tubes for making poles shall conftirm IO
grade YSt 240 or YSt 310 of IS : 1161-19791_ as appropriate, except that manual metal arc welding process may also be used to make the tubes and the cold bend test need not be carried out.
5.1.1 For mechanical tests the tubes shall be sampled in accordance with IS: 4711-19742, depending on the number of tubes in the lot to be inspected.
5.2 Stepped Poles - Stepped poles shall be made from one length of tube, seamless or welded, the diameter being reduced in parallel steps by passing the tubes through series of dies. Where welded tubes are used they shall have one longi- tudinal weld seam only.
5.3 Swaged Poles - Swaged poles shall be made of seamless or welded tubes of suitable lengths swaged and joined together. No circum- ferential joints shall be permitted in the individual tube lengths of the poles. If welded tubes are used they shall have one longitudinal weld seam only; and the longitudinal welds shall be staggered at each swaged joint.
5.3.1 Swaging may be done by any mechanical process. The upper edge of each joint shall be chamfered off at an angle of about 45”. The upper edge need not be chamfered if a circum- ferential weld is to be deposited in accordance with 5.3.2.

IS : 2713 (Part I) - 1980
The deflection, permanent set and drop test shall be conducted in succession on each of the poles selected.
10.1.3 Dejection Test-Each pole shall be rigidly supported for a distance from the butt end equal to the depth to which it is to be planted in the ground, It shall then be loaded, as a canti- lever, and the appropriate deflection load (SH Tables 1 to 4 of Part II, and 1 and 2 of Part 111) applied, at right angles to the axis of the pole 30 cm from the top ‘for poles up to 9 m long (overall), and 60 cm from the top for poles over 9 m (overall). For convenience in testing, the pole may be fixed horizontally and the load applied verti- cally. The temporary deflection due to the applied load at the point of application of load shall not exceed 157.5 mm.
10.1.4 Permanent Set Test - This test shall be carried out immediately after the deflection test. After application of proper load specified in Tables 1 to 4 of Part II, and 1 and 2 of Part III the permanent set measured from the zero position after the release of the appropriate applied load, at the point of application of the load, shall not exceed 13 mm.
10.1.5 Dro@ Test - This test shall be made in the case of swaged poles. The pole shall be drop- ed vertically with butt end (bottom end) down- wards, three times in succession from a height of 2 m, onto a hardwood block 150 mm thick laid on a concrete foundation. The pole shall not show any signs of telescoping or loosening of joints.
10.2 When the pole is tested horizontally and the load applied vertically, suitable allowance may be made to take account of the overhanging weight of the pole. The weight adjustment shall be calculated by the following formula:
-& I: 1, { H” - (4 - 4 - 4)” 1 + W I (1s - ld2
3 - (13 - I, - J2)2 1 + w, (13 - 1p-j where
WI, W,, W, are the weights per metre of top, middle and lengths of tubes respectively. The other symbols are as shown in Fig. 2. lr, I,, I,, H, J1 and J2 shall be expressed in metres.
11. RETESTS
11.1 Should any of the poles first selected fail to pass any-of the tests specified inJO.1, 4.1 of Part II and 4.1 of Part III two further poles shall be selected for testing from the same lot in respect of each failure. Should both these additional poles fail, the test material represented by the test samples shall be deemed as not complying with the standard.
12. WORKMANSHIP
12.1 When the tubes are made by manual metal- arc welding, the welders employed shall be quali- fied.

NOTE-When the overall length, the depth to which the pole is to be ‘planted, the number and disposition of the wires, the wind pressure and factor of safety to .be allowed for, have been decided; the dimensions of the pole suitable for the given working conditions for tangent or straight line locations may be readily calculated.

A-3. WIND LOAD of conductors above GL being 7.0 m. Wind pressure
A-3.1 First the load on the wires is calculated by is 1000 Pa (approximately 100 kgf/ms).
multiplying the wind pressure by the diameter of A-4.1.1 Calculation each wire, by the length of the span and the result by 213 to allow for circular section. Then the
Wind pressure = 1000 Pa (100 kgf/m2)

Equivalent load acting at A-A = Q -&$ N 3
Therefore, P2 = bnsdh N 150 1s

So, total load P = (PI + P2) N
A-3.3 The selection of poles shall be made from Tables 1 and 2 of Part II and part III for high strength poles and from Tables 3 and 4 of Part II
~for mild steel poles.
A-3.4 It is not possible to calculate the pole dimen- sions directly because they depend on the total wind load, which includes both the wind load on the wires and that on the pole itself, while the wind load on poles trial and error.
obviously depends upon process of
= 1140+241)=138ON(138kgf) at7mfromGi. For a mean height of 7 m .of the conductors,
a 9 m pole is suitable. For 540 TP 26 (see Table 1 of Part III), we have
step lengths as 4.8 x 2.1 x 2.1 m, the diameter of steps as 1143 x 88.9 x 76.1 mm and a crippling load of 2 220 N. This pole has planting depth of 1.5 m and A-A is 0.3 m from top or 7.3 m from GL.
Therefore, wind load on wires calculated as above and when transferred to be acting at
A-A=P, =‘F = 1340N(l34kgf).
NOTE - The cross arm is assumed at 75 cm from top and height of conductors above cross arm as 25 cm.

ling load according to Indian Electricity Rules, 1956, the working load of pole selected should
not exceed 2$$=1 110 N:
Therefore, this pole is not suitable. Taking the next pole, 540 TP, 38, we have the
diameter of steps as 139.7 x 114.3 x 88.9 ‘mm and crippling load as 3 320 N (339 kgf) the rest of the data remaining the same.
Wind load on wires transferred to be acting at A-A remained the same, namely, 1 340 N. Load due to wind on pole after transferring it to act at A-A

A-4.1 Required to select a suitable pole to carry ling load as above, the working load of pole selected
three-phase conductors of diameter 7.10 mm and 3 320 should not exceed - =

Similarly it will be found that 540 SP 28 will be suitable.
