Abstract (en)
An anti-theft device (10) for electrical cables, which comprises two toroidal transformers (11, 12) which are arranged so that each one surrounds an end portion of an electrical line (D): - a first toroidal transformer (11), at a first end of the electrical line, for transmitting an electrical control signal, - a second toroidal transformer (12), at the opposite end of the electrical line, for receiving the control signal. The first toroidal transformer (11) and the second toroidal transformer (12) are connected to a control unit (13) for controlling and managing the signals emitted by the first transformer (11) and for detecting and interpreting the signals received by the second transformer (12). The device (10) comprises a capacitor (14) for the passage of the AC signal to be interposed between two non-connected electrical cables (E, F) of consecutive portions of the electrical line (D).
