Cooled down to temperatures of 77 K (-196°C) or lower, superconductors carry electric currents that are more than 100 times higher than the current carried by copper conductors. Furthermore, under DC conditions these currents are transferred without energy loss. The unique properties of superconductors can result in electrotechnical solutions which are fundamentally different to conventional technology. Our research is focused on how superconductors can be utilized to reduce energy losses and costs, or improve functionality of electrotechnical components.
