Contact us!
On September 14, 1973, the Electrical Engineering Company SAS (EMINSA) was established, as a result of a merger of Dominican capital with the Chilean multinational company “Hernan Briones y Compañía”. It was the first company established in the Dominican Republic for manufacturing and repairing electrical distribution transformers.

In 1979 the company acquired the machinery and equipment from Canadian General Electric, advised by the Canadian firm Ferranti Packard Transformers, introducing Pad Mounted transformers to the market, once again being the pioneers of the industry.
