Method for removing a shielding foil (K2) of an electrical cable (Ka) with a longitudinal axis (L), which cable has, going out from the longitudinal axis outward, at least one inner conductor (K5), a dielectric (K4), the shielding foil (K2) and an insulating sheath (K1), whereby the cable (Ka) preferably has a shielding braid (K3) between dielectric (K4) and shielding foil (K2), comprising the following steps: a. Creating an incision (EK) of a first depth (T1) in the insulating sheath (K1) of the electrical cable (Ka), for example by means of the rotating blades of a rotary stripping apparatus , whereby the first depth (T1) is smaller than or the same as the thickness of the insulating sheath (K1); b. Creating a predetermined breaking point (S) in the shielding foil (K2) through pressing in of at least one radially adjustable perforation tool through the incision (EK) produced in step a. until the perforation tool has reached a second depth (T2), whereby the second depth (T2) corresponds to at least the thickness of the insulating sheath (K2) plus at least half of the thickness of the shielding foil (K2); c. Tearing the shielding foil at the predetermined breaking point (S); and d. Removing the shielding foil (K2), whereby the perforation tool is connected to means for detection of a contact with an electrically conductive object, whereby after detecting contact with the shielding foil (K2) or with the shielding braid (K3), the perforation tool is advanced radially by a predetermined value in the direction of the inner conductor (K5) of the electrical cable. comprising the following steps: a.
