が、後の取扱い性にまさる。FIG. 1 is a perspective view of a specific example of a self-supporting cable according to the present invention, and FIG. 2 is a perspective view of a fitting member in FIG. A main cable 1 having a plastic outer coating layer 12 on a cable core 11 and a suspension line 2 having a plastic outer coating layer 22 on a tensile wire 21 are arranged in parallel at an appropriate interval. Then, the main body cable 1 and the suspension line 2
Are integrated by fitting a pre-formed plastic split fitting member 3 at appropriate intervals. Further, a molded portion 4 is formed on the outer periphery of the fitted member 3 by injection of a plastic material, and is fixed so that the fitted member 3 is not detached. At this time, if the length of the cable of the injection mold part 4 in the longitudinal direction is shorter than that of the fitting member, the handling becomes easier later.

る。In the above-described self-supporting cable according to the present invention, when it is necessary to separate the suspension line from the main body cable when the cable is laid over the telephone pole and retained, a nib is formed on the mold on the fitting member. Thus, the fitting member can be easily removed from the main body cable and the suspension line by making a cut along the fitting portion or by shaving off the mold portion near the fitting portion. At this time, since the fitting member is located below the molded portion in removing the molded portion, there is no possibility of damaging the outer coating layer of the main body cable and the suspension wire. Furthermore, after the fitting member is removed, there is no particular need for post-processing, and a preparatory operation for easily and safely retaining the power pole can be performed.
