[0044] Meanwhile, when the power distribution work is completed, the worker can loosen the second fastening bolt (62) in the reverse order of the above to separate the horizontal extension rod (30) from the pole (P), loosen the first fastening bolt (60) from the rear part of the protective plate (10) to separate the vertical extension rod (20) from the protective plate (10), release the insertion part (14) of the protective plate (10) from the crossarm (B) to separate the protective plate (10), and then retrieve the insulating protective device (100) for the pole.

[0045] As described above, the insulation protection device (100) for a utility pole according to the present invention can simply be coupled to the crossarm (B) of the utility pole (P) to protect the equipment (C, I) of the utility pole (P), thereby preventing safety accidents by preventing the construction steel pipe scaffolding (S) or a part of the worker's body from coming into contact with the high-voltage power line due to the worker's carelessness.

[0046] In addition, the present invention allows the installation position of the protective plate (10) to be easily changed or adjusted by adjusting the lengths of the vertical extension rod (20) and the horizontal extension rod (30) during power distribution work.

[0047] The present invention does not require protective plates with different structures for each piece of equipment, and its simple structure makes it easy to manufacture and handle, thereby improving the efficiency of power distribution work and reducing operating costs.
