Protective Device for a High-Voltage Cable, High-Voltage Cable, High-Voltage On-Board Power Supply and Motor Vehicle

A high-voltage cable for a high-voltage on-board power supply, comprising:

• at least one electrical conductor;
• a shielding conductor;
• and
• at least one protective device, the protective device being arranged between two high-voltage-cable sections which each have a conductor section and a shielding-conductor section,
• wherein the protective device comprises:
• a cut-out for interrupting the at least one electrical conductor of the high-voltage cable in a fault scenario;
• a shielding element for forming a cable shield with the shielding conductor of the high-voltage cable;
• and
• a housing to be arranged between the two high-voltage-cable sections of the high-voltage cable, in which housing the cut-out and the shielding element are arranged and which has contacts for connecting the cut-out to conductor sections of the at least one conductor and for connecting the shielding element to shielding-conductor sections of the shielding conductor, wherein
• at least a part of the housing is capable of being non-destructively detached from the high-voltage-cable sections in order to enable an exchange of at least the cut-out in the case of a defect of the cut-out.
