TRIPLEX

For hard-to-reach indoor installation locations, MGM offers Triplex Indoor VPI Transformers. These can help reduce or eliminate unnecessary site tear down and reconstruction  by fitting a standard-sized unit into tight-spaces. 

To accomplish this, MGM uses single-phase VPI transformer modules in a banked assembly. They can be customized to suit your application requirements and provide the same proven methods as our standard three-phase transformers. 

All units are factory pre-assembled and tested to guarantee proper fit and performance, before they are disassembled for shipment. Our enclosures can also be knocked down to further facilitate movement and allow them to fit through tighter spaces and areas with limited entry points.
