Overview
Polemount Transformers
Polemounted transformers are the standard for single-phase and three-phase power distribution across much of the US, North-America and Latin-America market. QXG have UL certificate.
QXG liquid-filled polemount transformers are designed, built, and tested in accordance with all applicable IEEE, ANSI, CSA standards. Each unit is built to comply with the latest DOE efficiency regulations. They are ideal for utility applications requiring single-phase and three-phase distribution.
