Drives Isolation SCR Transformers MGM Transformer Company has earned the respect of the major drives manufacturers as a supplier of reliable, high quality drives isolation transformers. All transformers are custom designed to meet the customer’s exact specifications, using the latest ANSIIEEE criteria for harmonic loads. Derated standard distribution transformer designs are never used. As a design-and-build transformer company, we pride ourselves on our large and experienced engineering staff. Their extensive experience in the drives industry has resulted in our success as a supplier of these special transformers. Applications ranging from pumps and fans, to heavy duty-cycle steel rolling mills, have been designed and manufactured. We manufacture both liquid filled and dry type, from 15kVA to 7.5MVA. Our customers benefit because we are able to provide the best solution for any specific application.

• RANGE 3-PHASE200kVA-7,500kVA, 5kV to 34.5kV

To meet the demands of drives applications, special design and manufacturing processes are utilized. Engineering’s approach is to account for worst case scenarios, assuring conservative designs leading to long transformer life, even under severe applications. Manufacturing utilizes special winding techniques and equipment along with precision assembly and blocking methods, to maintain electrical and mechanical integrity while under stress. MGM Transformer Company specializes in working with drives manufacturers to design and supply transformers to meet their exact equipment requirements. Once specifications are determined, a matrix of designs and pricing can be established for the manufacturer, streamlining the ordering process. With a product range to10, 000kVA in both liquid-filled and dry type, and an engineering staff capable of designing to most any application, MGM Transformer Company is positioned as a leader in drives isolation transformer manufacturing.

Whether it is a Unit Substation or a standalone transformer, MGM has a solution for those hard to reach indoor installation locations. MGM’s Triplex Indoor VPI Transformers can help reduce or eliminate unnecessary site tear down and reconstruction to be able to fit a standard design transformer, thus reducing installation costs amounting to thousands of dollars. MGM’s Triplex Indoor VPI Transformers uses single-phase VPI transformer modules in a banked assembly. They can be customized to suit your application requirements and solve the challenges of hard to reach at indoor installation locations. The core and coil construction utilizes the same proven methods as our standard three-phase transformers. All units are factory pre-assembled and tested to guarantee proper fit and performance, and then they are disassembled for shipment. Our enclosures can be knocked down to further facilitate movement and allow them to fit through tighter spaces and areas with limited entry points. With MGM’s Triplex Indoor VPI Transformers there is no concern of liquid spills or need to build special liquid containments andor vault type electrical rooms.
