Single-Phase Pad-Mount Transformer Brochure

Introduction： 

The single-phase Pad-Mount Transformers of Bizoe（Yangzhou）is designed to improve the performance of the KVA rating: compact dimensions, lighter weight, safety and sustainability, among other aspects. There is no power distribution room, it can be placed directly indoor or outdoor, or on the street green space, reliably ensuring personal safety, both power supply facilities and decorative environment. Widely used in residential areas, commercial centers, stations, airports, factories, enterprises, hospitals, schools and other places. It is a smaller box-type transformer, suitable for outdoor installation without additional protective enclosure, and complies with the following standards: IEC60076, ANSI/ IEEEEC57.12.00, C57.12.20. C57.12.38,C57.12.90 etc.
