  Conventionally, when fixing an electric wire to a utility pole, the binding wire is wound around the pin insulator and the electric wire while positioning the electric wire in the vicinity of a pin insulator (fixing member) fixed to the electric pole. Has been done.

  Since this type of bind wire needs to be firmly fixed, it is shaped in advance into a spiral shape along the outer periphery of the object to be wound, such as an electric wire or pin insulator, and is parallel to the extending direction of the electric wire. By rotating the end portion while maintaining the posture, the electric wire and the pin insulator are positioned and fixed in the spiral shape (see, for example, Patent Documents 1 and 2).

  This bind wire is covered with insulation because it is wrapped around a transmission line carrying high-voltage current, but if it is deteriorated by exposure to wind, rain, sunlight, etc., it will be in a charged state because it is made of a metallic material. There is a case.

  In addition, since this bind wire fixes the electric wire to the pin insulator fixed to the armrest etc. of the upper part of the utility pole, the insulation coating may be damaged by the bird etc. that has stopped on the armrest. In such a case, the battery may be charged.

  In this way, it is dangerous if the bind line is in a charged state, and if a bird or the like stopped on a metal armor touches the bind line, a ground fault may occur. .

From this, when discovering a bind wire having deteriorated insulation, a curing sheet having insulation (see, for example, Patent Document 3) is used as an insulation sheet, and the insulation sheet is temporarily wound. Insulation is ensured by this.
