Low voltage transformers are manufactured in vacuum impregnation or in vacuum pressure impregnation (VPI) technology, depending on the application. These transformers are used in many standard and special applications, in commercial buildings, on board of vessels as well as in deep mines and industrial environments. Transformers with higher power rating are usually protected in appropriate enclosures sometimes equipped with air-forced, water-forced (AFWF). In the power range applications include galvanic separation or voltage adaptation.
All products are in accordance with industry and international standards and comply with Hitachi Energy quality requirements.
