                                                              for submersible pump, consisting of a fluororubber sheath, a

                                                              consists of a fluororubber sheath 1, a filler 2, a wire rope and
                                                              a signal cable; the wire rope and the signal cable are arranged
                                                              in a central region of the cable; and the filler 2 is filled in
                                                              the surrounding, and the fluororubber sheath 1 is extruded
                                                              outside the filler 2. The wire rope is formed by stranding a

         helps separate the coating 12 from the cable wire 14 and al-
         lows a place for the waste coating 12 to go. An air cylinder
         fires pulling on the top locators 24. As the top locators 24 go
         up the springs in the bottom locators 26 push them up and
         the cable wire 14 is pulled with them. This separates the
         coating 13 from the cable wire 14. The die 20 then returns
         to the top position and the air cylinders are returned to
         their start positions.
