A feed device for supplying electrical power and/or data to an electrical load, which is movable in at least one travel direction relative to the feed device, via cables. An electrical line cable carried along by the electrical load can be connected or is connected to the feed device, and to a power supply system for supplying the movable electrical load. The line cable can be output or retrieved from a reservoir, which is carried along by the load, in accordance with a distance between the reservoir and the feed device. The feed device has at least one connection part, which is rotatable about at least one pivot axis, for the line cable. This feed device, as well as a power supply system having such a feed device, provides protective guidance and storage of the line cable, reducing the risk of kinking or excessive bending of the line cable when moving the electrical load.

A spool device (60, 90) for storing at least a portion of a telecommunications cable (800) in a storage configuration (870) includes a base (100, 600), a spool member (300, 700), and a loop engaging member (440, 740). The base (100, 600) includes a plurality of cable holders (110, 110x, 110y, 110a, 110p) configured for receiving a first portion (822, 822a, 822p) and a second portion (824, 824p) of the cable (800). The spool member (300, 700) is mounted to the base (100, 600) and includes a wrapping area (314, 714) that is configured for storing a coiled portion (826) of the cable (800). The loop engaging member (440, 740) is configured for engaging a looped portion (828) of the cable (800) and thereby secures at least the coiled portion (826) and the looped portion (828) of the cable (800). The spool device (60, 90) may be used as an adjustable overlength device for looped cable. The spool device (60, 90) may store and dispense the cable (800) while ends (802, 804) of the cable (800) remain connected to stationary first and second devices (902, 904), respectively.

A line supply arrangement for electrically powered motor vehicles includes an electric line on a support arm above the motor vehicle. A trolley on the support arm positions the electric line such that a free end thereof hangs down from the trolley for connection to the motor vehicle and charging of an energy store. The trolley is movable relative to the support arm in horizontal direction or the support arm is movable and the trolley relative to the support arm in horizontal direction. Arranged on the trolley is a line reel to lower the free end of the electric line to the motor vehicle, and a hose reel is fixed on the support arm for supply and discharge of cooling liquid to and from the electric line. The trolley is movable relative to the hose reel. A heat exchanger is arranged distal to the trolley for cooling the cooling liquid.

A coil spring cassette includes a stator housing part and a rotor housing part that is rotatable relative to the stator housing part about a longitudinal axis. The stator housing part and the rotor housing part together form therebetween a first chamber and a second chamber at respective positions along the longitudinal axis. A first flat cable with a reversal of winding direction is arranged in the first chamber. A second flat cable with a uniform winding direction is arranged in the second chamber.
