    Dry Type Transformer

    Dry Type Transformers in South Dakota

    We design our medium-voltage dry type transformers to operate for decades. They offer suitable protection against short circuits and premature failure. Dry type transformers use air, rather than oil, to cool their internal environment and prevent overheating. They come with our top-industry five-year warranty, giving you the reassurance you need in your power supply. Your operation will also benefit from:

    • Low fire risk: With coils protected by a polyester vinyl coating and the elimination of oil, these devices reduce the possibility of a fire, making them ideal for chemical plants and forested areas.
    • Contamination-free operation: Dry type transformers pose no risk of leaks, ensuring the integrity of the surrounding environment.
    • Straightforward installation: These systems are simple to install, helping to reduce your time spent without a transformer.

    Padmount Transformer

    Padmount Transformers in South Dakota

    Many organizations use padmount transformers in public areas to connect to underground power lines. They are installed outdoors on a concrete pad without the need for a fenced-in enclosure. These transformers come with lockable front doors to protect the internal electrical components from the elements and secure them from tampering.

    We maintain a large inventory of padmount transformers with ratings of 500 kVA to 2,500 kVA. Our units offer a cost-efficient solution, going above and beyond all national energy efficiency standards. We can also retrofit these devices with accessories, including:

    • Temperature and liquid level gauges
    • Pressure vacuum gauges
    • Current sensing fuses
    • K-factor designs
