Electrical cable and manufacturing thereof

Abstract

Low-loss lightweight high-power kilohertz alternating-current high-voltage electrical cables 1 usable in low pressure having a bundle 2 of metallic wires 3 being separated from each other by non-conductor layers 4 provided on the individual metallic wires, wherein the metallic wires 3 alternate between outer positions 5 and inner positions 6 in the bundle along a longitudinal extension 7 of the electrical cable in order to counteract skin effect in the electrical cable bundle 2, as well as enabling counteraction of proximity effect, when in use, an inner semi-conductive layer 8 of broad range temperature rated polymeric material surrounding said bundle 2 of metallic wires 3, and an insulating layer 9 of broad range temperature rated polymeric material surrounding and bonded to the inner semi-conductive layer 5, at least one of the metallic wires 3 being in electric contact with the inner semi-conductive layer 8 as well as a manufacturing method.
