Our transformer re-manufacturing service offers a new lease on life for used transformers, enabling them to be completely rebuilt and returned to as-new condition or even upgraded to a higher specification. A re-manufactured transformer provides the same performance as a new transformer at a much lower cost, but the main advantage is RESA Power Service’s fast turnaround times that can have a re-manufactured transformer shipped in around one-third of the normal delivery time of a new unit
