Generally, in the electric pole installed on the ground, a rack band is provided to horizontally lay low-voltage electric wires to be wired in 2-wire, 3-wire or 4-wire, and the low-voltage electric wire is connected to the rack band to prevent shaking It is connected between the pole and the pole with the deflection of the low-voltage wire being left unchanged.

However, since the above-mentioned rack band is installed on the pole, the low-voltage electric wire comes into contact with the street lamp installed between the pole and the pole, and thus there is a risk of a safety accident due to a short circuit.

In particular, the height of the street lamp is 7 to 12 M and the shape is defined as a straight line. When the street lamp is installed between the pole and the pole, the arm, which is the upper curved portion of the street lamp, It is difficult to secure a separation distance even if the contact is not made, so that contact is frequently generated when a low-voltage electric wire is flowed due to an external pressure such as wind.
