"These new HVDC transformers will enable our customer to raise its system to a new level of energy efficiency and reliability," says Beatrix Natter, CEO of the Siemens Transformers Business Unit. "We are proud that the customer has placed the order with us as a reliable technology partner." Siemens will install the new units to fit precisely in the system. For example, the wall openings for cooling all devices are located at different points. In addition, all transformers will be equipped with a sprinkler system for fire safety.
All four transformers are being manufactured in the Nuremberg transformer factory. This factory has many years of experience in building transformers and manufactures HVDC transformers of all sizes up to a voltage level of 1,100 kilovolts (kV), which is currently the world record in transformer manufacturing.
