The invention relates to an electric cable, comprising at least one power line (1) having a first end and a second end, comprising multiple cores (11a, 11 b, 11 c, 11d), wherein each core has a core insulation and all core insulations (12a, 12b, 12c, 12d) are enclosed by a common sheath (13), and the sheath is surrounded by an oversheath (14), wherein the oversheath comprises a material, which is selected from the group consisting of silicones, perfluorocarbons, mica, glass fibers, metal fibers, ceramic fibers, and mixtures thereof, a first plug connector (2), which is arranged on the first end of the power line (1), and at least one second plug connector (3a, 3b), which is arranged on the second end of the power line, wherein the plug connectors (2, 3a, 3b) each are completely coated with the oversheath and comprise a polyurethane (PU), which contains a flame retardant, and a first connecting nut, which is arranged on the first plug connector (2), and at least one second connecting nut (5), which is arranged on a second plug connector (3a, 3b), wherein the connecting nuts each comprise a perfluorocarbon. The combination of materials according to the invention results in an extraordinarily high resistance of the electric cable with respect to the conditions of welding use. Therefore, it is suitable in particular for use as a control line for a welding device. |
