| 1 | M&L for refixing /reallingment of aluminium/GI/Copper strip in any size fixing on saddel type insulator using nut and bolt and washers reveting by aluminium revet for jointing to strip /laid in trench fix on surface or wall etc as site requirement making circuit continuity with making straight. Complete all as specified and directed. Note: Cost of insulator is included in Quoted rate .Porcelain type insulator and fixing screw shall be provided @2 nos per RM | 120.00 | RM |
| 2 | Materials and Labour for Supply and installation & testing of fast copper bounded earth electrode maintenance free chemical earthing having 3 mtr long copper pipe of minimum diameter 76 mm. There should be terminal for connection of 20 mm x 3 mm of copper strip with two holes of 14 mm diameter. FAST ELECTRODE is duly fitted with the highly conductive material with sealing at both ends with lead terminals of 20x3 mm copper strip at top, BFC (Backfilling compund chemical), earth conductivity enhancing compound alongwith Minimum 6 bags of 25 Kgs each of earth enhancing compound, including drilling a bore in earth of dia 300 mm dia. The chemical should be tested and certified by any international accredited laboratory. The earthhencing compound should be tested referring to protocol IS 1350/&/EC62321/111/54/CDV. The PH value of compound should be between 7 to 8. The content of mercury (Hg) & Hexacromium should be below detection level. The FAST ELECTRODE shall be dully tested & Certified by CPRI (Central Power Reserch Institution), Govt of India for a suitable minimum short circuit current for 1 second with initial pick of suitable KA. The Fast ELECTRODE shall be approved by CPRI, ERDA/NABL Lab including pit cover light weight made out of high quality polymer with lid made of FRP, including nessary testings and commissioning, complete all as specified and as directed. Notes:- (i) The work of earthing shall be carried out by authorised trained rep of OEM. | 12.00 | Each Job |
| 3 | Notes for Item No 2.00 contd... (ii) The acceptable earth resistance at earth busbar/ test point shall be as per users requirement as desired by Engr-in-Charge but it should be below 01 Ohm. At certain locations, it may not be possible to achieve desired earth resistance with one electrode / pit due to higher soil resistivity,in such cases, provision of loop earthing consisting of more than one earth electrode pits shall be done. The number of pits required shall be decided based on the resistivity of soil and resistance achieved for the earth pits already installed. The distance between two successive earth electrodes shall not be less than 3 metres. (iii) The procedure mentioned here-in-before for one earth pit shall be repeated for other earth pits. (iv) Additional earth electrode pits and loop conductor shall be measured and paid seperately. (v) Earth strip size 20mmx 3mm for making connection/tripod and up to 5 Mtr from earthing set (vi) Testing for earth resistance shall be carried out in presence of GE and Engr-in-Charge. (vii) Taking out existing unserviceable earthing system complete. (viii) Original purchase vouchers for copper rod and back fill compound and manufacturer test certificate of entire quantity shall be produced by the contractor before commencement of work. (ix) The Earthing shall be carried out with Soil suitable for Agricultural purpose. is deemed to be included with unit rate of item beyond 5 mtr earth strip will be measured and paid sepearatly. | ||
