Whenever there is a difference in the Standards the most stringent criteria shall apply.



  • Materials used in the manufacture of all the equipment shall be new and best quality and class most suitable for performance under the specified conditions.
  • Steel used for manufacture of various equipment shall be in conformity with the general requirements relating to the supply of materials laid done in relevant international standards.
  • The material analyzed in accordance with ISO 13520:2015 or other relevant international standard shall not show sulphur and phosphorous contents of more than 0.060% each.
  • Equipment shall be well-finished, clean and free from harmful surface defects. Ends of steel poles, angle sections etc. shall be cut square and shall be straight.
  • The bolts, nuts & pack washers and guy wire strand & cross arm guard wire shall be hot dip galvanized as per ISO 1461:2009(en) or other relevant international standards. The quality of zinc shall be at least Zn 98 grade specified in ISO 752:2004. The zinc coating shall be adherent, smooth, reasonably bright, continuous and free from such imperfections and flux, ash and dross, inclusions, flake and black spot, pimples, lumpiness and runs.
  • The steel poles shall be hot dip galvanized with minimum 125 micron thickness of zinc coating and steel base plates with minimum 125 micron thickness of zinc coating generally as per ASTM A123 and tested as per relevant international standards..
  • The articles shall withstand minimum 4 dips of one minute duration. The uniformity of galvanized coating shall be determined by the preece test as prescribed in ASTM A123.
  • Suspension and Tension Fittings shall be made of Aluminum Alloy and all nuts and bolts shall be made of hot dip galvanized steel with minimum thickness of zinc coating of 85 micron as per ISO 10684:2004(en) Part XIII or other relevant international standards. Fabrications and Finish

  • Poles shall be fabricated by cold bending of steel sheets of appropriate size and length in to octagonal shape and single continuously welded joint. The welding shall be done in an inert atmosphere preferably under a nitrogen jacket.

ii. All welding, cutting, machining, and fabrication shall be done prior to galvanization.

  • The Poles shall be straight, smooth, octagonal and conical and shall be well finished, clean, and free from burs, indentations and other surface defects.
  • Holes and earthing arrangements shall be provided as per structure drawings. All holes and pole top shall be blocked with plastic plugs / tightly fitting plastic cap to avoid entry of water into the hollow of the pole.
  • Two M-12 earthing studs placed diametrically opposite and flush welded with internal surface of the pole; complete with M-12 GI Nut, Bolt, Plain and Spring washer set, shall be provided each at 2700 mm below pole top and 500 mm below ground level in HV line poles and at 400 mm below pole top and 500 mm below ground level for LV line poles.

vi. Ground level shall be marked with a 12 mm wide paint strip all around in black color.

  • A prototype pole as per approved design shall be fabricated and tested at an authorized approved test bed as per IEC: 60652 or may be mutually agreed up to breaking load in the presence of the inspectors of the Client before proceeding with mass fabrication of the poles.
