Description

{Distributing Board Supporting Steel Bar}

The present invention relates to a wire harness for supporting a wire for power distribution, more particularly, to a wire harness for preventing a bird from sitting on a power line or nesting a wire, The present invention relates to a wire harness for supporting an electric power distribution board.

Generally, a large power generated by a power plant is transmitted to each substation at a high voltage through a power transmission line such as a power transmission tower, and then transformed at various stages in a substation so that a cable can be used for each household or building. And the distribution process that will be supplied to each region.

Normally, a high-pressure transmission cable, that is, a working wire is coated with an aluminum spiral bundle and a synthetic resin covering layer covering the outer periphery of the spiral bundle, which is connected to a pole to transmit electricity from a power plant or a substation to each customer And the like.

In this case, when the working wire is installed on the electric pole or the switchboard, the insulator is normally installed in order to block the sag due to the load and the electrical contact with the coarse iron. In order to reduce stress concentrated on the working wire and to prevent disconnection of the working wire In addition, since the birds are easily accessible to the wax iron, the parts and the machined wires are easily damaged by the algae, so that maintenance and repair costs are high.

As described above, with respect to the wrought iron structure in which a normal working wire is installed, in the publications of Korean Patent No. 1000031 and No. 1194832, there is provided a protruding portion that rotates periodically on the insulator portion supporting the working wire, Which is configured to prevent the wire from breaking through the operation of a device for buffering the flow of the working wire by detecting the pressure applied to the working wire when the tension is changed by the wind.

However, this technique can not completely block the approach itself because the periodic rotating protrusion rotates only in a fixed path, so the bird can adapt over time. Also, when the tension of the working wire due to wind changes, There is a risk that there is still a risk of disconnection at the time of contraction and expansion because expansion and contraction in the longitudinal direction are accompanied.

Further, in the case of the "fixing insulator for supporting the transmission wire" described in Japanese Patent Registration No. 116,1001, a pressing block, etc. including a complex fitting such as a connector and a fastener must be installed in order to fasten the working wire to the insulator. But also there is a problem that there is a possibility that even if only a weak impact is applied, there is a possibility of breakage because a separate buffering function is lacking.
