In a welding current cable of coaxial type, the conductors for one current direction are arranged essentially parallel to each other and freely movable transversely with respect to each other as a conductor bundle located centrally in the liquid-impermeable cable casing. The central conductor bundle is surrounded at a distance by a textile body, similar to a wrap knit stocking, with annular cross section and running along the length of the cable. The textile body has on its outside radially projecting longitudinal ribs between which the conductors are laid for the opposite current direction. In the spaces between cable casing, conductors and textile body, coolant flows along the length of the cable, and the porous textile body also permits transverse coolant flow. |
