Single-Phase Overhead Transformer
Our Features
Oil-filled single-phase overhead transformers are designed and manufactured to step down utility distribution voltages, which typically range from 2400 to 34500 volts, to lower utilization voltages. While some transformers are utilized for reducing voltages for commercial and industrial purposes, such as 277, 240/480, 2400, and 4800 volts, the majority are employed for stepping down to the single-phase voltage of 120/240. Additionally, these transformers find applications in small substations and various miscellaneous uses, and they can also be utilized to step up voltages when necessary
