Generally, large power generated in a power plant is transmitted to each substation with high-voltage power through a power transmission line such as a power transmission tower, and then transformed at each substation into several stages of transforming process. Which will be supplied to each region through the distribution process.

For the electric power supply to each customer, which is the final stage of the distribution process, there are a special high voltage distribution line for distributing the high voltage of 22.9kV and a commercial power distribution line of 230V or 380V A pneumatic transformer is installed between the high-voltage distribution line and the commercial voltage distribution line to support the voltage distribution line, and the high-pressure is decompressed to the commercial voltage to distribute to the respective crowded areas through the commercial voltage distribution line and finally to the commercial voltage distribution line And power is supplied to each customer through a lead wire.

Here, the lead-in line is composed of a working wire or a ground wire in consideration of the type of the customer and the regional characteristics.

In the conventional method in which the lead wire is composed of the underground wire, the down wire connected to the commercial voltage distribution wire is cut along the electric pole, and the lower end is connected to the lead wire installed in the underground channel or electric power source buried in the ground.

However, in the past, the reduction line along the electric pole has been wrapped in a semi-cylindrical synthetic resin pipe, and a method of protecting the synthetic pipe by fixing the synthetic pipe to the electric pole has been used.

However, when the cutter is protected by a synthetic resin pipe, the synthetic pipe can easily fall off, so that not only the cutter can not sufficiently protect the cutter, but also the number of the cutter is limited.

In addition, as a prior art for protecting the cut line, Korean Registered Patent No. 10-0987424 (Registered on Jun. 10, 2010) "Provision of Processing Distribution Line for Prevention of Electric Shock Accident" and No. 10-1319935 (Registered on October 14, 2013) &Quot; Process distribution line insulator for prevention of electric shock accident "and No. 10-1355102 (registered on April 14, 2014)" Process distribution line insulator for prevention of electric shock accident "are attached to the outer surface of a strut A first elastic pad and a supporting stone protruding from the outer surface of the first elastic pad at a predetermined length so as to fix a second processing distribution line (cut line) drawn out from the first processing distribution line and buried in the ground, And a second processing line (cut line) from the external force while attaching the supporting projection of the first elastic pad, which is fixed to the outer surface of the first elastic pad and is holding the second processing line (cut line) By means of fastening means Provided with a shock-proof protective member having a portion provided with a second resilient pad is defined machining distribution line protection and protecting the cut line as well it discloses a technology that enables to prevent electric shock.

However, the prior art has a problem that the supporting force is not sufficient because the prior art is configured to support the cut-off wire while passing between the support protrusions.

In addition, since the fastening means for fastening the processing power distribution preventing portion and the working distribution line protecting portion to the electric pole use a fastening means called a so-called "mummy ring", the fixing to the electric pole is not firmly performed, There is a problem that the processing power distribution control section, the processing distribution line protection section, and the cut-off line are damaged and the original function is lost.

Therefore, a plurality of outgoing wires connected to the power distribution lines are collectively connected through the incoming wires, so that the outgoing wires can be easily installed on the pole and the outgoing wires flowing the abnormal currents can be individually blocked. It is possible to prevent accidents such as connection failure or short circuit by minimizing the shaking of the drawing wire by the wind and to prevent an electric shock accident because the drawing wire can not directly contact the passersby passing around the electric pole And it is required to develop a technology that can prevent the ordinary people other than the persons concerned from being easily dismantled, thereby preventing damage to the outgoing wires.

The inner diameter of the inner cylindrical portion 811 of the inner supporting member 810 and the outer cylindrical portion of the outer supporting member 820 are smaller than the outer diameter of the inner cylindrical portion 811 of the outer supporting member 820, Since the outer supporting member 820 is formed in a tapered shape corresponding to the shape of the electric pole 10 so that the outer supporting member 820 is slid downward relative to the electric pole 10 and the outer cylindrical portion 821 is inserted into the inner cylindrical portion 811 The covering process can be smoothly performed.

The outgoing wire 600 and the outgoing wire support and the electric shock preventing means 800 can be installed in advance before the pole 10 is installed and the coarse iron 20 and 110 are installed.

Since the lead wire 600 is supported by the lead wire support and the electric shock preventer 800 including the inner support member 810 and the outer support member 820, the lead wires 600 can be prevented from being shaken by the wind It is possible to prevent an accident such as a connection failure or a short circuit of the outgoing wire 600.

The lead wire 600 is not exposed because it is surrounded by the outgoing wire support and the electric shock preventer 800 including the inner support member 810 and the outer support member 820. Therefore, There is no possibility of direct contact with the lead wire 600, so that an electric shock accident can be prevented.

On the other hand, in the illustrated example, a plurality of outgoing electric wires 600 are disposed radially in the lower portion embedded in the ground as shown in Figs. 1 and 3 to 6, The inner horizontal support groove 814 formed in the inner lower flange portion 813 and the outer horizontal support groove 824 of the outer lower flange portion 823 are formed parallel to each other in accordance with the distribution of the customer or the required distribution direction, And the lower end portions embedded in the ground of the electric wire 600 may be arranged in parallel.
