elsco today manufacturer

ELSCO was founded in Cincinnati in 1912 as a transformer repair company. In 1988, after more than seven decades of repairing other systems, we decided it was time to build our own. Today ELSCO is a major manufacturer and supplier of medium-voltage power transformers in 500 – 2500 KVA ratings.

We are one of the few power transformer providers in the USA that designs, manufactures and stocks high quality copper-wound dry-type transformers that meet or exceed DOE BIL and efficiency standards.

We strive to maintain 95% in-stock availability so that we can quick-ship any unit from our Cincinnati plant within 24 hours of receiving an order.

Whether it’s a manufacturing plant, hospital, higher education campus, utility company or electrical contractor, ELSCO serves to maintain efficient electric power to our customers across North America.

Our Dry Type Transformers Are Hand Made in the USA

We begin with quality materials:

  • CRGO laminated magnetic core.
  • High-conductance copper windings.
  • Dupont Nomex insulation rated at 200o C.
  • SG 200 Fiberglass solid insulation for molds and barriers.

We are one of the few manufacturers that hand-wind our transformer coils. We do it for a reason.

We don’t trust automation to get the job done right. Automated manufacturing can produce poor-quality devices that are more likely to fail. That’s why every dry type transformer we produce is carefully handcrafted by our team of experts and tested five times before it is shipped or placed in stock.

Customer Benefits of ELSCO Hand-Made Construction

  • Higher electrical efficiency – from tight, uniformly concentric coils.
  • Greater surge and short-circuit protection – from premium insulation.
  • Cooler operation – from compliance with airflow clearance specifications.
  • Quieter operation – from tight mechanical assembly and lower magnetic induction designs.
  • Longer useful life – from avoiding hot spots that can cause premature failure.
