Remanufacturing
Transformer Remanufacturing

RESA Power re-manufactured transformers provide the same performance as a new transformer at a much lower cost.

The RESA Power Transformer Re-manufacturing Service offers a new lease on life for this used Olsun Electrics Dry Pad Mount 75 KVA Transformer, enabling it to be completely rebuilt and returned to good-as-new condition, or even upgraded to a higher specification. A re-manufactured Pad Mount Transformer provides the same performance as a new Pad Mount Transformer at a much lower cost. However, the main advantage is RESA Power's fast turnaround that can have a re-manufactured transformer shipped in approximately one third the normal delivery time of a new unit.

The cost of our re-manufactured transformers will vary from case to case, but typically we would expect to have you back in service at between 60% and 70% of the cost of a new unit. However, it is delivery rather than cost that will be crucial factor for many customers, especially as the current growth in world-wide demand for HV equipment is resulting in ever-increasing delivery lead-times. We can have a re-manufactured power transformer shipped in around 2 to 3 weeks after the order is placed. That's one third of the 12 week delivery schedules now being quoted for new small and medium power transformers.
