[0001] DISTRIBUTION LINE SUPPORTING BAR STRUCTURE OF ELECTRIC POLE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bare iron structure in which a distribution line for supplying electric power to a customer can prevent secondary slip during a broken line.

Electricity produced or developed in the power plant is supplied to general consumers or factories such as end users through power transmission lines and distribution lines through the process of boosting.

Since electric power that can give a risk is flowing in the power distribution line, it is common that the power distribution line is separated from the ground so as to be located at a relatively high position because it is fixed to the insulation insulator provided on the top of the pole.

The distribution line is installed at a high position and is managed relatively safely, but can be directly impacted on the distribution line due to carelessness when working with crane, excavator, ladder, etc.

When the above-mentioned strong impact is applied to the distribution line, the connection between the insulation insulator and the distribution line is canceled and the distribution line is broken or the distribution line is cut off when the distribution line is severely broken, An accident may occur.

In addition, this problem may occur because the coupling between the insulator and the solid iron is released.

As a conventional technique for partially alleviating the impact applied to the insulator as described above, a number of such insulators have been disclosed as well, including an insulated-type insulator for a distribution cable, Korean Patent Registration No. 10-0873746 (December 12, 2008).

If there is a problem that the distribution line breaks in case of bad weather, there is no structure that can hold the distribution line, so if the broken distribution line falls down to the surrounding trees, ground, or water, There is no way to solve the problem.

In addition, in the related art, it is inconvenient that the installed wire can not be redirected, so that it is inconvenient to install another wire to the support when connecting the distribution line to the customer.
