Abstract
An electrical superconductor comprises in a stepwise manner single conductors and at least two stages of stranding of component cables and interstitial layers having a high resistance relative to the conductivity of the matrix material arranged between the single conductors and/or the component cables. The electrical resistance of the interstitial layers from inner twisted single conductors to the interstitial layers of the outer component cables are made progressively higher in at least two consecutive interstitial layers in order to effect a reduction in electrical losses in an economical manner.
