本発明は光通信機能を具備した架空送電線、架
空地線等の光複合架空電線の製造方法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing optical composite overhead wires such as overhead power transmission lines and overhead ground wires equipped with optical communication functions.
この種光複合架空電線は、複数本の金属素線を
撚合せてなる架空電線内に光ケーブルを配置して
なる。 This kind of optical composite overhead wire is made up of an optical cable arranged within an overhead wire made of a plurality of metal wires twisted together.

周に複数本の金属素線を撚合せる方法や光ケーブ
ルを中心以外の位置に配置するように光ケーブル
と金属素線を一緒に撚合せる方法が採用されてい
る。尚、光ケーブルはアルミニウム等の金属管内
に遊嵌状で収納される場合もある。 Conventionally, in the manufacturing method of this optical composite overhead wire, for example, the optical cable is placed at the center and multiple metal wires are twisted around the outer circumference of the optical cable, and the optical cable and the metal wire are placed at a position other than the center. A method is used in which the strands are twisted together. Note that the optical cable may be housed in a metal tube made of aluminum or the like with a loose fit.
しかしながら、上記のような方法は、撚線工程
や電線の延線工程での作業は光ケーブルを存在さ
せた状態でなされるため、撚線加工時の圧縮力や
延線の際の金車通過時に受ける圧縮力等により光
ケーブルが損傷する恐れがあつた。 However, in the above method, the work in the wire twisting process and electric wire drawing process is done with the optical cable present, so the compressive force during the wire twisting process and the wire passing through the metal wheel during the wire drawing process are affected. There was a risk that the optical cable would be damaged due to the compressive force, etc.
一方、近時光ケーブルを配置すべき位置にパイ
ロツト線を撚込み、撚線工程や延線工程の終了時

イロツト線を引抜くと共に光ケーブルを引込む方
法が提案されている。 On the other hand, a method has recently been proposed in which a pilot wire is twisted in the position where the optical cable should be placed, and at the end of the twisting process or wire extension process, the optical cable is connected to the end of the pilot wire, and the pilot wire is pulled out and the optical cable is pulled in. has been done.
この方法によると、光ケーブルを撚線工程や延
線工程で損傷する恐れは無くなる。 According to this method, there is no possibility that the optical cable will be damaged during the twisting or drawing process.
しかしながら、パイロツト線と光ケーブルとの

欠点があつた。 However, since the connection between the pilot wire and the optical cable is simply by fixing the two terminals with a connecting sleeve, the strength of the connection between the pilot wire and the optical cable is low, and there is a risk that the two will be separated when they are pulled out. In addition, if the connection sleeve is made thick and long to increase the connection strength, the rigidity of the connection part and other parts will differ greatly, and if the overhead wire with pilot wire is curved, However, the optical cable and pilot wire at the end of the connection sleeve are bent at an acute angle when pulled out and pulled in, and this part gets caught on the surrounding metal body, making it impossible to pull out and pull in the pilot wire and optical cable smoothly.
本発明はこのような欠点を改良したものであ

効果を奏する。 Accordingly, the present invention provides a method for manufacturing an optical composite overhead wire in which an optical cable is placed in an overhead wire made by twisting a plurality of metal wires, in which a material of the same type as the outer layer material of the optical cable is placed at a position where the optical cable is to be placed. A pilot wire made of material is arranged, and then a predetermined length of the end of the pilot wire is made thin, and a hollow portion having approximately the same length and the same diameter as the thin diameter portion is formed at the end of the optical cable along the axis. The thin diameter part of the pilot wire is inserted and fixed into the cavity, and then a connection tape is fixed between the edge of the pilot wire and the edge of the optical cable, and then the pilot wire is pulled out from the overhead wire and the optical cable is pulled in. This work can be carried out in the absence of an optical cable when passing through a gold wheel during wiring or extension, thereby not only preventing damage to the optical cable, but also providing the following special effects.

Even when the pilot wire and optical cable are connected together, the entire pilot wire, optical cable, and the connecting portion between the two curve smoothly, and the connecting portion does not get caught on the outer metal body as in the conventional case, making it possible to smoothly exchange the pilot wire and optical cable. I can do it.
