Rashtriya Ispat Nigam Limited has invited bids for the electrical maintenance of shaft kiln equipments in crmp inspection, condition monitoring, defect list generation, and subsequent preventive maintenance of the shaft kiln material charging systems, material discharging systems, bag house purging systems, bulk loading spouts of material handling systems, and dampers. items 11 through 16 dictate the strict preventive maintenance schedules for facility motors segmented explicitly by power thresholds, ranging from minor motors rated under 5.0 kw up to heavy-duty operational motors rated between 180.1 kw and 520 kw. broad plant operations are addressed via items 17 through 22, which require inspection and condition monitoring for the kiln feed building (kfb) equipment, the flux storage building (fsb) equipment, the waste gas cleaning system (wgcs) equipment, the dedusting (de) system equipment, blowers, inner cylinders, and booster equipment. physical infrastructure updates and critical logistics are handled under items 23 through 28, specifying the exact safe removal and installation protocols for operational motors under 200 kw, alongside providing vital supportive physical labor to cme personnel during the replacement of heavy motors rated 200 kw and above. general site safety, system longevity, and auxiliary distribution networks are structured through items 29 to 42, which encompass the replacement or fault rectification of trailing and festooning power/control cables for cranes, hoists, and tripper cars, the mandatory condition tracking and preventive maintenance of lightning, electronic, and general earth pits at the crmp-2 facility, the systematic laying and termination of low-tension (lt) copper or aluminium power cables up to 185 sq mm sizes on site racks and trays, execution of straight-through cable joints, building or overhauling various control boxes and hanging pendents, checking 1-to-5 ton hoists and 2-ton cranes, and servicing complex plant-wide utility, single-phase, and welding sockets. facility illumination parameters are managed under items 43 through 52, which mandate routine maintenance of local lighting systems across designated structures including the kiln feed building, lime screening building, lime storage building, flux control room, gas mixing house, booster house, gas ramps, kiln proper, wg systems, de systems, conveyor galleries, the new substation building, local mcc rooms, cable vaults, drive rooms, and plc control areas. finally, items 53 to 60 wrap up the extensive maintenance criteria by establishing strict requirements for structural electrical maintenance at the lcss, individual mcc panels, pdbs, mldbs, and eldbs, the thorough mechanical overhauling of manual or electrically operated 3/4 pole air circuit breakers (acbs) ranging from 600 to 3200 amps, targeted fault-finding and internal wiring rectifications for electrical panels utilizing component switches or relays under 110 amps and above 110 amps, and the detailed preventive maintenance of 750kva converter transformers (lt side) and 100 kva lighting transformers via cleaning, terminal tightening, and diagnostic insulation resistance (ir) value mapping. The estimated project cost is ₹0.39 Cr. Please refer to the tender document for EMD details. Interested bidders can submit applications until 24 September 2026, with the technical opening scheduled for 25 September 2026.
