Founded in Cincinnati in 1912 as a transformer repair company, ELSCO Transformers now designs, hand-builds and stocks medium-voltage power transformers for industrial and commercial customers. Since building its own dry-type units in 1988, the five-generation, privately owned company has paired in-house engineering and testing with a 95% in-stock availability target, often shipping replacements within 24 to 48 hours. That repair heritage also shapes ELSCO’s retrofit, custom bus-work and emergency replacement support when a failed transformer threatens operations.
