Temperatures close to absolute zero are not a precondition for obtaining superconductive properties in some materials. Groundbreaking scientific research showed that certain ceramics become superconductive at “higher” temperatures of around -150 ° Celsius (123 Kelvin). This research was awarded a Nobel Prize for physics in 1987. Cooling HTS to their operating temperature is easier and less costly, opening up a wide range of possibilities for technical HTS applications. Twenty years of research and development have turned HTS wire into a product offering an economy that is superior to copper wire in many areas.
