Description

  The present invention relates to a branch wire support tool, and more particularly to a branch wire support auxiliary tool used to support a branch line with a support structure in a structure for branching an electric wire from an overhead wire.

  Electric power is supplied to an electric user such as a general household by being branched and drawn as a low-voltage branch line from an overhead electric wire supported by a support structure such as a so-called utility pole. This branching is carried out in a desired direction by once attaching an electric wire branched from the electric wire installed between the electric poles to a pull-in armature fixed substantially horizontally to the electric pole.

  FIG. 5 shows an example of a branch structure in such a utility pole. As shown in the drawing, ordinary three-phase AC electric wires 52-1, 52-2, 52-3 for supplying electric power to a general home or the like are stretched on the utility pole 50. And it branches in the vicinity of the utility pole 50, respectively, and is pulled down as a low voltage | pressure pull-down line (low voltage | pressure branch line) 100-1,100-2,100-3. Such a branch line is a cross-linked polyethylene insulated vinyl sheath cable generally called a CV electric wire, and various thicknesses such as 22 mm and 60 mm are used.

  In addition, a retractable arm 200 is fixedly attached to the utility pole 50. The pull-in arm 200 has a length of about 1 m, and the low-voltage branch lines 100-1, 100-2, 100-3 are guided along the pull-in arm 200, and the pull-in arm 200 Are led to the user side as lead-in lines 300 respectively from both ends.

  The low-voltage branch line 100 is attached to the lead-in arm 200 in a state where a plurality of branch lines 100 are bundled along the lead-in arm 200, and the bind wire 400 is used at a predetermined position. . That is, the bundled branch lines 100 and the pull-in armor 200 are both bound together by winding the bind line 400 a plurality of times. The bind wire 400 is, for example, a copper wire coated with vinyl or the like, and has a diameter of about 1.6 mm. And the winding attachment of this bind wire 400 is performed in one place or a plurality of places of the pull-in exclusive arm 200.

  Various proposals have been made on the structure for branching from the electric wire installed on the power pole to a general household. For example, in Patent Document 1, a high-level optical fiber cable for drawing an overhead optical fiber cable into each home is proposed. A subscriber lead-in method is disclosed that allows the work to be performed only once in the first place. That is, the aerial cable is branched at the upper part of the utility pole in the first one-time work, and the branched subscriber cable is pulled down and connected to a wiring connection box installed near the ground of the utility pole. Then, the subscriber lead-in wire is led out from the lower part of the wiring connection box, wound around the tension member, and attached to the middle part of the tension member. It is hooked using various members.

  In this way, the subscriber lead-in line that is retained at the top of the utility pole is drawn from there to a nearby subscriber's house, and the subscriber lead-in line is connected at the time of extension work after only the first cable branch work at a high place. The work can be performed from the ground using a kite.
