潰されるおそれがあシ、接続上問題がある。However, in the former structure, it is not easy to accommodate the optical communication line within the metal wire, and there are problems in terms of manufacturing and cost. Furthermore, if the optical communication line is inserted into the stranded metal wire, there is a risk that the optical communication line inside will be crushed when the stranded metal wire is crimped and connected, which poses a connection problem.
また、後者の構造では風圧で通信線が撮動し、金属線撚
線に打ち当って損傷され易い欠点がある。In addition, the latter structure has the disadvantage that the communication line is easily damaged by wind pressure when it hits the stranded metal wire.

The optical communication line 4 is housed in the twisting groove 3 on the surface of the twisted metal wire 2 and twisted together, and the outer periphery of the twisted metal wire 2 with the optical communication line 4 twisted on the surface is made of metal. It has a structure in which a conductive pressing layer 5 made of mesh is provided. As the optical communication@4, for example, a fiber-reinforced plastic layer is provided on the outer periphery of an optical fiber via a buffer layer, and the outer periphery is further coated with tetrafluoroethylene plastic, silicone resin, or the like.

−弛みが生じでも垂れ下るのを防止することができる。Since such an optical composite overhead line has a structure in which the optical communication line 4 is accommodated in the twisting groove 3 on the surface of the twisted metal wire 2, it can be easily manufactured by simply twisting and matching. In addition, even if the optical communication line 4 is subjected to straining with a metal wheel or the like during installation, the optical communication line 4 is accommodated in the twisting groove 4 of the stranded metal wire 2, so that it will not be damaged by protection from the stranded metal wire 4. can be prevented. ]-Also, it is possible to prevent the occurrence of a situation where the original optical communication line vibrates due to wind pressure and hits the stranded metal wire 4. In addition, the outermost layer 4'i
Due to the presence of the presser foot J'Vk 5, it is possible to more effectively store the optical communication line 4 from straining, and to prevent the optical communication line 4 from sagging even if the optical communication line 4 is loosened.

熱性の光通信線４を用いておれば問題はない。Furthermore, since the optical communication line 4 exists on the surface side of the stranded metal wire 2, when crimping the stranded metal wires 2 to each other, the optical communication line 4 is pulled out from the stranded metal wire 4 at that point. By keeping it in a safe place, you can prevent it from being damaged during connection. Further, even if the stranded metal wire 2 generates heat when a large current υ flows due to a lightning strike during use, there will be no problem as long as the heat-resistant optical communication line 4 having the structure described above is used.

金属線撚線で保護することができる。As explained above, the optical composite overhead line according to the present invention has a structure in which the optical communication line is accommodated in the twisting grooves on the surface of the twisted metal wire, so it can be easily manufactured by simply twisting and matching. Also, when crimp-connecting twisted metal wires, pull the optical communication line out of the twisting groove at that point to prevent damage to the optical communication line due to (5). be able to. Furthermore, the stranded metal wire can protect the optical communication line from being subjected to stress during installation.
