FIELD: electrical engineering.
SUBSTANCE: invention is related to the field of electric engineering, in particular, to superconductive cable, which contains frame (2), layer (3) of superconductive conductor formed around external periphery of frame (2), insulating layer (4) formed around external periphery of conductor layer (3), screening layer (6) formed around external periphery of insulating layer (4), and normally-conductive metal layer (5) formed between insulating layer (4) and screening layer (6). Normally-conductive metal layer (5) is located inside the screening layer (6), has inductivity higher than of screening layer (6).
EFFECT: provides suppression of temperature rise in case of accidents, such as short circuits, and reduction of AC losses in normal mode of operation, since high currents flow through screening layer.
