PROJECT SUMMARY
SECTOR:
Mining
CLIENT:
HudBay Minerals – Snow Lake Lalor Mine
DURATION OF PROJECT:
2 Weeks
PROJECT SUMMARY:
Hudbay Minerals is a diversified Canadian mining company producing copper concentrate and zinc metal in its operating facilities located in Manitoba and Peru. It owns and operates three polymetallic mines, four ore concentrators and a zinc production facility.
Dynamo was retained by HudBay Minerals to refurbish one (1) 30 MVA, 115–25 kV power transformer. Work included the removal of all mineral oil and re-gasketing of all flanged connection points including: all HV and LV bushings, temperature thermal wells, cooling radiators, inspection covers, and oil piping. The transformer was placed under vacuum and dried prior to filling with hot, filtered oil through a mobile oil process unit suitable for refurbishing oil at a rate of 6,000 L/hr. Once the transformer was completely filled, the oil was circulated to further condition the oil and transformer windings. A full set of electrical tests was then completed, and the transformer was back online within ten (10) days.
