A high voltage system for an electrified vehicle includes a first high voltage component, a second high voltage component, and a high voltage cable. The high voltage cable provides power between a first location of the first high voltage component and a second location of the second high voltage component. The high voltage cable includes a core, a sheath disposed around and along the core, and one or more detection layers at least one of (a) disposed around and along the sheath or (b) disposed within the sheath. The one or more detection layers are configured to facilitate detecting at least one of (a) damage or wear to the sheath or (b) a location of the damage or wear along the sheath.

A cable with a signal detection function includes an core, a second insulating layer, and a signal detection layer. The signal detection layer is for transmitting signal data. The cable further includes a second insulating layer, and plural signal detection layers provided for transmitting signal data. The signal detection layer and the cores are disposed inside the second insulating layer, and the signal detection layer is cladded with plural cores. If the first insulating layer in the signal detection layer is damaged, the signal detection layer will be electrically connected to the conductor assembly. The cable with the signal detection function can detect the abnormality of the core through the signal detection layer to facilitate maintaining and repair the cable.

A 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.
