Renewable energy transformers

Alternative renewable energy is growing rapidly worldwide and Alfa Transformer has been serving this market for more than 20 years. We offer special GSU transformers for the solar, wind, geothermal, and biogen power markets. These applications require special design considerations because of the internal and external stresses placed upon the transformers.
