Pioneer manufactures Three-Phase Pad-Mounted Transformers up to 10 MVA at 69 kV (350 kV BIL). They can be designed for radial or loop-feed applications, in a live-front or dead-front configuration. When Bay-O-Net fuses are required, the unit will have a hinged hatch above the fuses to reduce the tank height to a minimum. All units comply with either CSA or IEEE standards.
