Dry Type Transformers

The Most Advanced Power Transformers on the Market

Dry-Type-TransformerWhat Are the Basics of Dry Type Transformers?

Transformers change voltages from one level to another.  Most commonly, that change involves very high-power line transmission voltages (500 kV) being reduced to the much lower levels used in heavy industry (as much as 30 kV).  Dry type, or air-cooled, transformers accomplish this function so safely and efficiently that they are commonly used for indoor applications where other transformer types are considered too risky. Electric Service Company (ELSCO) is the leading manufacturer of and repair facility for dry type transformers.

For a more detailed overview of how dry type transformers work and considerations for choosing them over oil filled transformers, see our dry type transformers overview page .

What Are the Benefits of Dry Type Transformers?

ELSCO’s Dry Type transformers  deliver high efficiency performance which saves you money in the long run. Our transformers feature an advanced design – they are copper-wound – which provides quiet, cost-effective power output.

  • Increased Efficiency – Engineered to exceed all national energy efficiency standards including NEMA, ANSI and IEEE and surpasses the latest recommended Energy Star and DOE ratings.
  • Improved Savings – Reduces monthly utility costs and lessens the need for replacement and rigging charges.
  • Extended Life – ELSCO uses superior quality materials and expert workmanship in the manufacture of our transformers, including 3M Nomex insulation, Glastic fiberglass insulation and 100% copper wiring, round coil design and disk winding.
