DF Electric was founded in 1980 as a result of the concern of a group of professionals in the electrical sector. From the outset, DF Electric has represented the meeting point between the trust of their customers and suppliers and the motivation and hard work of the most highly qualified professionals.
Constant investment of resources in automation and modernisation of production lines is what has differentiated DF Electric from its competitors, as few companies of their size have developed their own manufacturing technology. What started out as a small project was affected by two events at the beginning of the 90’s which turned DF Electric into the company it is today.
