Design Precision
At Enerset Power Solutions, we provide power transformers with unique requirements that must be met with precision. Let our experienced professionals help with an innovative, competitively-priced solution to meet your specific needs.
For the design and manufacturing of our transformers, a 3D modeling is used to fully integrate all parts and components in a virtual basis and facilitate the assembly process. HiB grade silicon steel is used to deliver high efficiency in a compact design. Our transformers are designed to protect against environmental hazards. Our distribution and pad-mounted transformers are available in live-front or dead-front designs and radial or loop feed configurations.
