High-temperature superconductor technology(HTS) is the key technology fortomorrow’s electricity market. Compared with copper conductors, HTS ceramic cableshave a number of signifi cant advantages. For example they can conduct electric current without resistance at app. 200°C below zero. Transmission capacity is five timeshigher than that of conductors made of copper, while current loss is reduced to one tenth. The development of HTS cables is inseparably linked to the name nkt cables. However, nkt cables is not just one of the ...
