A liquid cooled cable (1) includes a conductor (2) with at least two cable strands (3). The conductor (2) is encompassed by a hose (5) spaced in a sectional view at least partially apart from the conductor (2) by an interstitial space (6). The interstitial space (6) is arranged between an inner wall (7) of the hose (5) and the cable strands (3) of the conductor (2). The interstitial space (6) conducts a cooling liquid (15) along the conductor (2).

The invention relates to an electrically conducting wire, the wire (4) being formed as a flexible helix with constant or changing slope, with constant or changing diameter and with straight or curved extension, wherein the wire comprises a superconductor. In this way, a wire is provided that comprises a superconductor and that allows small bending radii, especially lower than 15 cm.
