500 kVA Medium Voltage Dry Type Transformers

When a 500 kVA dry type transformer fails or reaches end of life, every hour of downtime carries a real cost. Sourcing a replacement that fits existing infrastructure and meets your exact specifications quickly is challenging. At ELSCO Transformers, we stock 500 kVA dry type medium voltage transformers ready to leave our facility within 24 to 48 hours, depending on what modifications need to be made. Combined with our custom-built, retrofitting and custom bus work capabilities, that availability supports faster power restoration and a solution built precisely to your requirements.

500 kVA Dry Type Transformer Overview and Features

ELSCO Transformers manufactures 500 kVA dry type transformers for medium voltage power distribution in commercial and industrial facilities. These three-phase, four-wire systems use air circulation for cooling, reducing the fire and contamination risks associated with oil-cooled systems. We hand-assemble our transformers and perform a five-stage production test, delivering quality solutions that can serve you for over 35 years.

Since we started building our own dry type transformers in 1988, we have recorded zero failures or warranty claims. Our systems meet and exceed DOE, IEEE, NEMA and ANSI standards, reducing energy costs and lowering your total cost of ownership over time.

Our solutions feature:

• Advanced design: The round coil primary construction and sheet-wound copper secondary offer short-circuit protection. A step lap mitered core operates at lower flux densities, reducing no-load losses and lowering energy costs across the transformer’s service life.
• 100% copper windings: Our primary and secondary windings use 100% copper, a superior conductor with high mechanical strength. This material allows your transformer to respond to surge events and heavy continuous loads without degrading, translating to fewer overheating events, reduced risk of unplanned failure and a longer period before replacement is necessary.
• DuPont Nomex and SG200 fiberglass insulation: Coil assemblies use DuPont Nomex rated to 200° Celsius and SG200 fiberglass solid insulation. These materials resist excessive heat and short-circuit stress, prolonging the system service life and reducing the frequency of corrective maintenance.

Plug-and-Play Installation and Support

While ELSCO Transformers does not install transformers, we engineer our retrofitted units for a plug-and-play installation. Before a unit leaves our facility, we confirm it can fit the existing enclosure and align with your electrical connections, simplifying the installation for your team. Our engineers are also available by phone 24/7 to answer your installation questions.

Applications of a 500 kVA Dry Type Transformer

At 500 kVA, our transformers are suitable for:

• Midsize manufacturing and process lines: Support individual production lines or automated process areas within a larger facility, where 500 kVA provides the rated capacity.
• Medical office buildings and outpatient facilities: Power smaller healthcare environments where critical equipment and safety systems require continuous uptime.
• Individual campus buildings: Step down voltage at stand-alone academic buildings, residence halls or administrative facilities on college and university campuses.
• Commercial and mixed-use buildings: Deliver consistent power to office buildings, retail centers and multiunit housing developments requiring dependable medium voltage step-down capacity.
