Wechselstromkabel mit verseilten elektrischen Leitern

摘要

The a.c. cable has at least one cable core (2) with a central support body (4) around which normal- or superconducting conductors (3) are stranded in at least three conductor layers (Lj). The conductors preferably have high-Tc superconducting material. The invention provides that the stranding angles ( alpha j) in the conductor layers (Lj) are selected so as to gradually increase or decrease from layer to layer in radial perspective. The cable core can advantageously be a concentric configuration of a forward conductor and return conductor.
