OIL FILLED TRANSFORMERS


Thanks to partner company Elettromeccanica Piossasco’s long experience our range of threephase oil-immersed transformers is able to satisfy even the most demanding customer requests in terms of:

  • Energy efficiency and consumption reduction;

  • Low noise;

  • Possibility of installation in tropical countries with temperatures up to +55°C;

  • Customized manufacture upon customers’ technical requirements;

  • Technical and sales assistance in project development.
