ELSCO Transformers has been engineering and manufacturing dry type transformers since 1988. Since then, our systems have not recorded a failure, demonstrating our commitment to providing you with quality solutions. ELSCO maintains a 95% in-stock transformer catalog, enabling you to complete emergency replacements with minimal downtime. Your investment can depart our building within 24 to 48 hours, contingent on any modifications needed.
What Sets Our Transformers Apart
ELSCO builds each transformer by hand, using materials selected for long-term performance. This approach allows uniform tightness, which contributes to higher electrical efficiency and helps prevent the hot spots that cause premature failure.
Each system is built with cold-rolled grain-oriented (CRGO) laminated magnetic steel, a material that minimizes iron losses and helps sustain efficient operation under continuous high-demand conditions. The higher electrical efficiency of our copper windings and CRGO core reduces energy costs over the transformer’s service life, contributing to a lower total cost of ownership.
We wind coils with 100% copper for both the high and low voltage windings and insulate them with premium-grade materials such as DuPont Nomex and SG 200 fiberglass, which are selected for long-term thermal stability. Our new indoor dry type systems carry a five-year warranty, reflecting our confidence in the quality of materials and workmanship behind our systems.
We assemble our solutions with airflow clearances to support cooler operation and fit them with anti-vibration pads to minimize noise and vibration during sustained loads.

Retrofit Services to Support Your Installation
We can retrofit your transformer to your enclosure type, bus bar alignment and other specifications, ensuring it will fit your existing space or enclosure, that all connections will line up and that the configuration meets safety requirements. This service helps you avoid delays and costly on-site rework. Our experts are available by phone to answer your installation and energization questions.
Applications That Run on a 3,750 kVA Transformer
Commonly found in operations where high-draw equipment runs continuously, and voltage stability is critical, 3,750 kVA transformers are ideal for:
- Automotive stamping and assembly plants: Power press lines, robotic welding cells and paint systems that require consistent and reliable voltage for precise operation.
- Paper and pulp mills: Deliver stable voltage across large motors driving pulpers, refiners and drying sections for continuous processing.
- Cement and aggregate production facilities: Run kilns, crushers and continuous conveyor systems around the clock to meet production deadlines.
- Cold storage and refrigerated distribution centers: Keep compressor banks running 24/7 to maintain consistent, high electrical loads and the required temperatures for product integrity.
- Semiconductor fabrication facilities: Maximize yield at different stages of microchip production with stable power for process control.
