    Who should use a unitized substation?

    A Delta Star unitized substation is perfect for a municipality that is planning to have an outage, additional seasonal or temporary power needs, or has special projects planned in the future. These substations are smaller than a power transformer, and built to give your utility an extra boost when needed.
