Rourkela Steel Plant Onsite Overhauling of 132KV/33KV Outdoor Transformers Tender 63MVA 62.5MVA 2026

Tender Overview

Rourkela Steel Plant, a division of Steel Authority of India Limited, invites bids for the onsite overhauling of 132kV/33kV outdoor transformers (63MVA and 62.5MVA ratings) at the RSP facility. Quantity is 6 units. The scope encompasses pre-overhaul testing, site dismantling, and complete overhauling activities including oil handling, OLTC inspection, DM box refurbishment, and core-coil inspections. No BOQ line items are published; testing will be performed onsite with bidder-provided equipment, while the power supply is arranged by RSP. This procurement targets reliable transformer maintenance with emphasis on oil testing, electrical tests, and rigorous reassembly.

Key differentiators include the comprehensive testing suite (IR & PI, ratio, tan delta, oil BDV/DGA) and complete onsite execution from oil draining to post-overhaul checks, ensuring transformer readiness for service after overhaul. The tender emphasizes safety with power isolation and work-permit controls, and requires bidder-owned equipment for testing and on-site operations.
