The invention relates to a device (). Said device has two machine parts () that are movable relative to one another and are connected to each other by a supply line () along which a sensor line () is mounted for measuring torsion of the supply line (); the sensor line () is connected to a measurement unit () which is designed in such a way that an electrical parameter (P) of the sensor line () is measured, the torsion being ascertained using said parameter (P). The invention further relates to a corresponding supply line (), a sensor line () and a torsion measurement method.

A monitoring system contains a safety cable that has at least one line along which a fault sensor device extends. The safety cable has a capacitor with two electrodes and an inductor which is made of a conductor that is electrically connected to one of the electrodes such that a series resonant circuit is formed. By ascertaining a resonant frequency of the series resonant circuit, the state of the safety cable, in particular the wear of the safety cable, is determined and a possible future fault is predicted in particular. A corresponding safety cable in particular in the form of a prefabricated material available by the meter and a method for operating the monitoring system are described.

A barrier layer is used against migration of a substance, wherein the barrier layer is arranged in a cable and/or around an electrical conductor, and the barrier layer contains polyethylene furanoate or solely contains polyethylene furanoate. Furthermore, an electrical conductor, a cable, and a method are used for manufacturing a coated cable or a coated hose and a use of polyethylene furanoate as a barrier layer.

The present invention relates to a data cable. An embodiment of the data cable comprises at least one wire pair and an internal element. The at least one wire pair has two wires running parallel in the longitudinal direction of the data cable. The internal element has at least one flat section. The at least one wire pair and the internal element are arranged in the data cable in such a way that the at least one wire pair lies against the at least one flat section of the internal element.

Data cable with internal element

A data cable has a specially formed stranded conductor, as a result of which the transmission properties of the data cable are significantly improved. The stranded conductor is surrounded by insulation and has an unpressed assembly composed of a plurality of individual wires which are of a same type and being embodied as external wires and being disposed around a center. The external wires are embodied with a non-round cross section, with a result that when viewed in cross section an extent of the external wires increases radially outward from the center.

Data cable and stranded conductor

A data line includes a first data cable, a second data cable and a connecting element connecting the first and second data cables to one another. A connecting element interconnects a first parallel pair data cable and a second star quad data cable. The connecting element has multiple connecting lines which transition mutually adjacently disposed cores of a respective transmission pair of the first data cable to diagonally oppositely disposed cores of a transmission pair of the second data cable.
