In 1996. Dimitrov founded the electric porcelain factory, again in the town of. Kazanlak, with main activity production of fixtures for low and medium voltage fuses. Gradually, the company adopts different types of insulators for low and medium voltage, necessary for the new production of disconnectors. In the late 90's, the company moved to a new building, which she remodels into her home. There is also the current headquarters of the company.
