         present application are shown. As shown in figure 14, the
         positions of the wire ropes and the signal cables are inter-
         changed with those in figure 13. The other arrangements
         are the same as figure 13. In this embodiment, the fluoro-
         rubber sheath may have a thickness of 0.4-1.2 mm, prefer-

         example 4 mm. The sintered membrane may have a thick-
         ness of 0.2-0.3 mm, preferably 0.23 mm, and a density of

         as figure 13. The conductor 4 may have a diameter of 1-3   roller rotates. A stand includes a top portion in contact or
         mm, for example 2.5 mm. The insulating bush may have a   physical communication with the frame and a plurality of
         thickness of 1.5-2.5 mm, preferably 2 mm. The wire rope has   legs which extend downwardly from the top portion, elevat-

         cable used for submersible pump may have a total diameter
         of 25-40 mm.
           As shown in figure 16, there are four wire ropes and four
         signal cables which are uniformly arranged in the circum-
         ferential direction of the cable. The conductor 4 may have a
         diameter of 4-8 mm, for example 6 mm; and the insulating
