Method for replacing an electrically conducting cable by another electrically conducting cable

摘要

Method for replacing a first cable (1) by a second cable (2) between a first predetermined point (1a) and a second predetermined point (1b), comprising: a. the provision of first series impedance means (S1) close to the first end (2a) and second series impedance means (S2) close to the second end (2b) of the second cable (2), which first (S1) and second (S2) series impedance means can be switched between a state of high impedance value and a state of low impedance value; b. electrically connecting the second cable to the first cable (1) at the first (1a) and second (1b) points, during which operation both the first (S1) and the second (S2) series impedance means are kept in their state of high impedance value; c. switching the first (S1) and (S2) series impedance means to their state of low impedance value before optionally removing the first cable between the first point and the second point, wherein both the first (S1) and the second (S2) series impedance means are impedance inducing means allowing induction of an impedance within a range from a low impedance value to a high impedance value without cutting through the second cable (2).
