The benefits of our dry type transformers originate from both the design and the materials used in their construction.

1. Experience, Quality Design, Materials and Craftmanship

ELSCO Dry Type transformers are hand-wound in 100% copper, with a disc-wound round coil, slotted comb, sheet wound secondary and a step-lap mitered core with low flux density. Nomex or film covered wire insulation is rated at 200°C and solid insulation is SG 200 fiberglass. or Nomex. Each unit is inspected and tested five times in the manufacturing process and again before shipping. This uncompromising commitment to quality produces tangible user benefits.

2. Highly Efficient Performance

ELSCO Dry Type Transformers exceed Energy Star and DOE energy efficiency standards and meet the latest NEMA, ANSI and IEEE standards. Their Basic Insulation Level (BIL) ratings are comparable to liquid-cooled transformers.

3. Run Cool and Quiet

The combined effect of precision hand-wound copper coils, a step-lap mitered core with lower flux density, and varnishing of the entire unit ensures minimal noise and vibration after installation. This is an advantage in many applications.

4. Long Useful Life

Superior quality materials, superior design and expert craftsmanship deliver long-standing performance. ELSCO Dry Type transformers come with a five-year warranty on materials and workmanship for indoor installations, and have an expected useful life of 35 years or more.

5. More Cost Effective

A superior quality design and construction results in:

Higher energy efficiency and quieter unit.

Lower utility and maintenance costs.

A longer useful life.

5 – 7 year payback due to higher efficiency and lower operation costs.
