Abstract
A cable drum for supplying energy to an electrically operated utility vehicle includes an axially extending winding body, a winding drive for rotatably driving the winding body for reeling-up or unreeling an electric line, a spacing means for segmenting a winding layer reeled-up onto the winding body, and an air conveying means for generating cooling air through a passage region. The cooling air flows outward of the interior of the winding body. The passage region is kept clear between adjacent segments of the winding layer.
