ABB TransformersPower Transformers - The largest installed base worldwideABB 2ABB Transformers. Unified power for your success.Power TransformersMost of the transformers supplied to the market by ABB use Core Type Technology. They are mostly used in customer applications as generator step up and system intertie power transformers.Large Power Transformers are defined within ABB as units with a three phase power rating higher than 200 MVA or with voltage ratings higher than 275 kV. ABB supplies three phase units up to 1100 MVA and single phase units up to 500 MVA. Power transformers for system voltages up to and including 800 kV have been delivered to the market since the 1970’s. HVDC Converter TransformersThe HVDC converter transformer is a key component in an HVDC transmission system. In addition to its normal application to provide transfer of power between two voltage levels, it serves a number of additional functions like galvanic separation between the AC and DC systems. A fairly large tapping range permits optimum operation also for a large variation in load without loss of efficiency.PolytransformerABB has developed a new product in the transformer world, The Polytransformer. This transformer is designed with multiple voltage ratings on the HV, the LV and tertiary side that allow it to work in substations and power plants at different voltages.Impedances and MVA ratings are chosen to cover most of the applications.Single phase and three phases units are available. Its compactness and flexibility of use make the Polytransformer the ideal universal transformer for any transmission and generation system.Customized solution by dedicated people in focused factories.Transformer Services81441012ABB3Shunt Reac...
