Generally, a bare iron equipped with an insulator at the upper end of a pole is installed in the transverse direction to fix and insulate the three-phase electric wire to the insulator of the bare iron. In order to replace the electric pole at the construction site with the electric power line of KEPCO, In case of changing (pin length - replace internal lead) and replacement of corroded wire (brass), replace the high voltage cable by installing the fastener on the pole in case of replacing the LP insulator, So that the user can perform the operation.

1, a horizontal band 121 including an insulator 123 is provided at an upper end of a vertical band 122, and a vertical band 122 including a vertical band 122 and a horizontal band 121 A pair of support rods 124 are provided to support both sides of the horizontal base 121 by the support rods 124. [ The clamp 120 is fixed and installed on the pole by the clamp device 130. The clamp device 130 is formed of a pair of the pole clamp 130a and the universal clamp 130b, Or by using a chain band or the like to fix or release the electric pole and the free leg. Here, the reference numeral 100 is a pole, the reference numeral 110 is a complete circle, and the reference numeral 110a is an insulator.

In the meantime, even when replacing the insulator installed in the bare iron, the electric wire replacing equipment, such as the above-mentioned bare bones and manpower, is inserted to lift all the wires of the three phases to secure the working space and replace the damaged insulator. Partial replacement work for one or two insulators of a dog has been performed after lifting all three wires through a complicated process using the burden. Therefore, compared to the replacement object, unnecessary use of equipment or manpower input results in remarkable economical deterioration, as well as troublesome work and complexity, resulting in a reduction in work time and a decrease in work efficiency.
