| Sl. No. | Item Description |
| 1 | Supply, Install, Commissioning & Testing of Advance Encapsulated Compound based CPRI type-tested Maintenance Free, Pipe-in- Pipe Technology upgraded (Zinc & Alloy Coated), ZINC COATED (80-100) Microns with pure Zinc (99.9%) & ALLOY COATING (150- 200) microns. Earthing System confirming IS 3043.The outer and inner pipe should be 76.2 mm & 41.9 mm dia, 3.0 mtrs Length, Zinc coated with additional Special Alloy coating 300 mm on the topside for additional protection of the Terminal. The annular space between the pipes being filled up with compact filled (Crystalline Conductive Compound). The compact filled mixture which is machine pressed in the pipes should disintegrate or collapse when outer pipe corrodes. The inner pipe should be extended with terminals for connectivity. The job includes digging the pits and refilling the same with 2 x 25 Kgs bags of BARON Electrodite Back Fill Earth Enhancing Carbon Based Conductive Concrete compound. The Back Fill Compound should be Electronically Conductive with Noncorrosive Properties & Environmentally Neutral Material. Electrodite Back Fill Compound shall be suitable to be installed in either slurry or dry form and shall not be mixed with any soil/cement etc. while pouring in the bore hole so that it improves conductivity of the earth electrode and ground contact area with & incl FRP Chamber & Cover complete all as specified & as directed & to the entire satisfaction of Engr-In-Charge. |
| 2 | The Back-fill material/compound shall have following characteristics :a) Resistivity 0.20 Ohm-meters as per Clause 5.4.1 of IEC 62561-7:2018b) Tested as per IEC : 62561-7 and the test certificates (Corrosion Test, Leach Test, Sulphur Test & Resistivity Test )shall be submitted to the Engr-In-Charge.c) Shall not depend on the continuous presence of water / moisture / salt to maintain its conductivity.d) Shall not decompose or leach out with time.e) Shall solidify when mixed with water and set like concrete.f) Shall not contain hazardous chemicals and necessary Test certificate from reputed accredited laboratories shall be submitted to the Engr-In-Charge.g) Shall not be affected by drought and shall be stable between -10˚ to +50˚ C temperature.h) Shall be suitable for any kind of soil.j) Shall be supplied in sealed, moisture proof bags. These bags shall be marked with Manufacturer’s Name or Trade Name & Quantity.\\"The following test certificates shall be submitted to the Engr-In-Charge by the Contr prior to supply of ELECTRODITECarbon based Back fill compound from an independent laboratory (NABL Accredited Laboratory) along with Routine Test Report :a) Corrosion Test Certificate as per IEC : 62561-7 b) Leach Test Certificate as per IEC : 62561-7c) Sulphur Test Certificate as per IEC : 62561-7 d) Resistivity Test Certificate as per IEC : 62561-7\\"Model - ASEEL-39 3.0 m length (ZINC & ALLOY COATED) of Make ELMECH or techno-commercially equivalent of ERICO/CAPE ELECTRIC/TRUEPOWER. |
