Siemens Energy leads the market not only because of its two outstanding HVDC converter station technologies, but also by manufacturing innovative HVDC converter transformers.
Taking into account the advantages of HVDC, such as reduced energy transmission losses and smaller footprint as well as reduced right-of-way costs, investments in HVDC equipment pay off easily. HVDC converter transformers can also be filled with bio-degradable ester fluids. The advantage, besides the improved green footprint, is the reduced fire hazard due to higher flash and fire points.
Deviations in winding geometry would significantly impact the performance and efficiency of the HVDC converter transformer, and therefore the whole HVDC system. This is why Siemens Energy develops, designs and manufactures its largest transformer class to the highest precision standards.
