Abstract: A high-power high-frequency cable (1) is provided with a strand (2, 3, 2?, 3?, 2?, 3?, 2??, 3??) made of electrically conducting individual wires (22) and a jacket (21) implemented as a conductor and surrounding the individual wires (22), wherein each individual wire (22) has an insulating varnish layer, wherein the high-power high-frequency cable (1) has at least one strand pair (2, 3, 2?, 3?, 2?, 3?, 2??, 3??) of which one strand (2, 3, 2?, 3?, 2?, 3?, 2??, 3??) can be used as a feed conductor and one strand as a return conductor, and wherein the feed conductor and the return conductor of the strand pair (2, 3, 2?, 3?, 2?, 3?, 2??, 3??) are bundled so as to run parallel to each other.
