nkt cables exhibited the HTS Triax(tm) Energy Cable product at the Hannover fair together with our Dutch partners Alliander/Liandon and the Technical University Delft. We took part in the “Superconducting City” theme stand.
Wednesday 6 April marked the 100-year anniversary of the discovery of superconductivity, which is why this day was dedicated a special “Superconductivity day” at the fair.
We chose to use this occasion as the “launching date” for presenting some very good results within the Dutch superconducting cable project. We announced our new world record for low losses in a superconductor for AC, a result achieved in our Dutch project focused on the installation of a 6 km long HTS Triax cable in Amsterdam. This means that we have designed and tested the most energy efficient superconductor cable ever.
Recently, the Japanese cable manufacturer Furukawa stated a record 0.3 W / m at 3000 Arms in a cable - like us, Furukuwa used 3 mm wide superconducting wires. We have now reached an even lower loss of only 0.11 W / m at 3000 Arms. This evidence, together with measurements of very low flow resistance in a 45 m long insulating tube (aka "cryostat") proves that it will be possible to manufacture and commission very long superconducting cable systems. "
The guests who visited our stand could experience that longer superconducting cables with smaller cooling systems now are possible.
