良に関するものである。Detailed Description of the Invention [Industrial Field of Application] The present invention provides a clamp attachment part for extending an optical fiber composite overhead ground wire, and a wire extension system for extending an optical fiber composite overhead ground wire using the wire extension clamp. It concerns an improvement in the method.

アイバに悪影響をおよぼすおそれがある。[Prior Art and Problems] When extending an overhead line, the messenger wire is stretched over the metal wheel of the tower to be overlaid, and the end of the messenger wire and the end of the electric wire are connected. A method is used in which the wires are connected and the messenger wire is replaced with an electric wire. In this case, in order to connect the messenger wire and the electric wire, a wire extension clamp is crimped onto the end of the electric wire. However, in this case, if the overhead wire to be extended is an optical fiber composite overhead ground wire 10 as illustrated in FIG. 2, the situation becomes quite complicated. That is, as shown in FIG. 2, the optical fiber composite overhead ground wire 10
A strand 3 is placed around the outer periphery of a so-called OP unit which stores an optical fiber 1 in an internal storage chamber 2a of a pipe 2.
Since the fibers are twisted together, if a wire drawing clamp is directly crimped onto the fibers, there is a risk of adversely affecting the optical fibers inside.

荷されないようにして延線を行つていた。 Therefore, when extending the optical fiber composite overhead ground wire 10, a special construction method as shown in FIG. 3 has been adopted. That is, the ends of the stranded electric wires are disassembled, the strands 3 and 3 are untwisted, the OP unit consisting of the optical fiber 1 housed in the pipe 2 is cut to expose it, and the cap 4 is attached to the end of the OP unit. After fitting the OP unit, apply a presser wrap 5 made of self-adhesive tape or the like to make it waterproof, then wrap the untwisted wires 3, 3 again and apply a metal-like material to the defective part where the OP unit was cut and removed. A rigid insertion rod 6 with high strength is inserted to form a wire compression section, and the compression section 21 of the wire drawing clamp 20 is crimped to the wire compression section so that the compression force of the clamp is not directly applied to the OP unit. I was running a line extension.

なるおそれが大きかつた。 However, according to the conventional wire stretching method described above, the OP unit is easily damaged when untwisting and untwisting the strands, and the winding part for waterproofing the OP unit inevitably becomes thicker.
It becomes difficult to wrap and twist the strands around this again, and in some cases, there is even a risk that the entire end portion becomes too thick to be inserted into the crimping hole of the wire clamp. Furthermore, when the twisted layer of the twisted wire is composed of two or more layers instead of one layer, there is a great possibility that it becomes even more difficult to dismantle or retwist the twisted wire.

It is an object of the present invention to provide a wire extending clamp attachment part for a ground wire and an improved wire extending method using the wire extending clamp.
