Abstract:
A method for removing a cable structure from a tube, using a cable lead-through apparatus which comprises a housing with an inlet opening, an outlet opening, and a pressure supply opening, said method comprising:connecting in a substantially fluid-tight manner a first end of the tube, from which the cable structure is to be removed, to the inlet opening of said apparatus;advancing an end of the cable structure that is nearest to the first end of the tube through the outlet opening of said apparatus by applying a negative fluid pressure through the pressure supply opening of said apparatus to the first end of the tube during a first period of time until the cable structure comes to a substantial standstill;removing the negative fluid pressure from the pressure supply opening of said apparatus; andfurther advancing the cable structure towards and through the outlet opening of said apparatus by applying a positive fluid pressure to the pressure supply opening of said apparatus until substantially a whole length of the cable structure is removed from the tube.
