Abstract
A cable drum has a rotating winder fitted in a mounting and a frequency converter fitted on the winder. At least one socket outlet of the winder is electrically coupled to the frequency converter and is supplied with an electrical spatial frequency. The integration of the cable drum and frequency converter makes it easier to transport the equipment by reducing weight and the number of pieces.
