High voltage substations

Substation installation

When SAG was established in 1997, the initial activities of the company were designing and installing 120kV substations. Since then, our activities have been expanded with equipment and complete field maintenance. Our two largest customers are ELMÜ and ÉMÁSZ, with some other major customers including E.ON-owned electricity suppliers. In addition to numerous high/medium voltage and medium/medium voltage substations for suppliers, we have installed several industrial and power plant substations, including applications in renewable energy production. Our high level of expertise is guaranteed by our employees’ decades of combined experience.
