WIRES FOR CABLES
Cable for HVDC transmission line
Advanced superconducting links for very high power transmission
Bruxelles, (Belgium), ongoing
The Best Paths project granted by the European Commission under the FP7 framework program, aimed to develop novel grid technologies to increase the European transmission capacity and electricity system flexibility. This was the first time a high voltage superconducting cable system has been designed employing as superconducting materials magnesium diboride. Apart form testing the suitability of MgB2 for high power electricity transfer, the remaining components (cryogenics envelops, insulation and terminations) have been also examined taking into account the real grid condition. The project confirmed that MgB2 can carry electricity up to 500 times more than copper, and that the wires are manufactured in a robust industrial process.
