Abstract: A high-voltage line for motor-vehicle high voltage includes an interior tube surrounding an interior cavity of the high-voltage line, an electrically conducting interior conductor surrounding the interior tube, an intermediate insulation surrounding the interior conductor, an electrically conducting outer conductor surrounding the intermediate insulation, and an outer insulation surrounding the outer conductor. The outer insulation, the outer conductor, the intermediate insulation, the interior conductor, and the interior tube are disposed coaxial to one another.

Abstract: In a method for the online determination of at least one rolling parameter when rolling a rolling material rolled along a rolling line in a rolling mill including at least two rolls on a roll stand, the rolling material is guided past or through at least one measuring device during the rolling, which interacts with a rolling material variable of the rolling material, the rolling material variable being changeable along the length of the rolling material, and outputs a measurement signal, wherein: (i) the measurement signal is transferred into the frequency space, and the rolling parameter is determined from the measurement signal transferred into the frequency space, and/or (ii) a frequency inherent in the change of the rolling material variable is determined from the measurement signal, and the rolling parameter is determined on the basis of the determined frequency.
