Abstract
A flexible electric cable for the electric power supply of planes on the ground is subjected to an unspooling and spooling process, the cable having a conductor layout including a plurality of insulated energy supply conductors which are arranged concentrically with respect to a longitudinal central axis of the generally circular in cross-section cable, several insulated neutral conductors which are arranged concentrically with respect to the central axis, and several insulated control conductors which are arranged concentrically with respect to the central axis. A non-metallic, tension- and compression-resistant support member is disposed at the center of the cable, which support member extends over the length of the cable. At least the energy supply conductors include CCA wires having a copper content of at least 15%.
