ル5の両FRP被覆2/J。In a recently developed optical composite overhead wire in which an FRP-coated optical cable for optical communication is incorporated into an overhead wire, the FRP-coated optical cable incorporated inside the optical composite overhead wire was damaged due to some reason, such as a broken wire, etc. in case of,
It becomes necessary to replace this with a new optical cable. Conventionally, as shown in FIG. 1, a predetermined length of the internal FRP-coated optical cable 21 is exposed from the terminal portion of the optical composite overhead electric wire 20, and the terminal of the new FRP-coated optical cable 22 to be replaced is inserted into the terminal of the FRP-coated optical cable 21. At the same time, the thin-walled vibrator 23, which has been inserted into the new FRII-covered optical cable 22 in advance, is drawn to the butt part of the old and new FRP-covered optical cables 21.22, and the FRP coatings of both optical cables 21.22 and the thin-walled pipe 23 are bonded with adhesive or the like. After connecting the FRP coated optical cables 21 and 22 to each other, pull out the old FRP coated optical cable 21 from the terminal of the optical composite overhead wire 20 in the direction of the arrow, as shown in Figure No. However, according to this method, the thin-walled vibrator 23 was placed over the
+FRP coated optical cable 21.22σ] Not only is the outer diameter of the butt connection part larger than the outer diameter of the FRP sheathed optical tables 21 and 22, but also the bending rigidity is greater, so that the curved part of the optical composite overhead electric wire 20 The method of the present invention was developed in view of the above points, and it is difficult to pass through the contact area, and it takes a long time to replace the old FRP-coated optical cable. To explain an example of this in Figure 1, in Figure 2, l is F in the aluminum pipe 3.
The RP coated optical cable 2 is inserted and protected, and the aluminum vibe 3
It is an optical composite overhead cable (for example, an overhead ground wire) formed by twisting and laminating aluminum or steel wires 4 on top, and what happens to the FRP-removed optical cable 2 incorporated inside the optical composite overhead cable after it is installed. Due to this reason, the stem 8L1. In that case, as shown in FIG.
Both FRP sheathings 2/J of the new FRP-coated optical cable 5 are exposed to the optical cable pull 2 and are to be replaced with said FRP-coated optical cable.
