    摘要： A composite hyperconductor for use at cryogenic temperatures and particularly well suited for AC applica­tions employs at least one filament of conductor having an extremely low electrical resistance at cryogenic tempera­tures, a strengthening matrix surrounding the conductor, and a barrier for electrically insulating the conductor from the matrix while providing for efficient heat transfer therebetween and preventing contamination of the high purity conductor during processing. The preferred composite hyperconductor for space applications comprises an ultra high purity aluminum conducting filament, a aluminum alloy matrix and a boron nitride barrier.
