Superconducting Cable Test to Proceed with Only One of Three Cables

A demonstration of high-temperature superconductor (HTS) cables at Detroit Edison's Frisbie substation will proceed using only one of three cables. Pirelli Energy Cables and Systems told DOE in mid-July that leaks in the cooling systems for the other two of the cables prevented their use. Pirelli halted the demonstration in January after initially discovering the leaks. The two non-functional HTS cables will be removed and replaced with their equivalent, six copper cables, to allow the test to proceed. Pirelli hopes to energize the cable by year-end.

American Superconductor Corporation, which provided the HTS wires for the cable, expressed disappointment but emphasized that the wires themselves met or exceeded performance specifications. See the American Superconductor press release (PDF 130 KB). Download Acrobat Reader.
