The present invention relates to an insulation distribution board box for a very hight voltage power line. An operator may operate using a receptacle installed at a distribution box body without carruing a receptacle connected from a ground by installing a distribution board including a breaker and a receptacle in a utility pole. The distribution board box includes a cabinet body disposed at a forward side of the utility pole; a cabinet provided at both sides of the cabinet body and including a door guide pocket having an open front surface and a lock piece formed at upper and lower portions of a front side; a slide hinge block slidably installed at upper and lower portions of the door guide pocket and including a protrusion locked with the locking piece and a hinge piece formed therein with a hinge hole; a pair of doors to open/close right and left sides of a front opening portion of the cabinet body half by half, inserted into the door guide pocket and having a hinge hole corresponding to the hing hole; and a hinge pin inserted into the hinge hole. When the operator opens a door on a working table to perform working, the door is inserted into a door guide pocket included in the cabinet of the distribution board box. Although strong wind is generated, the door is not fluctuated. When the door strikes the operator, injury or falling accidents may be prevented and walkers may be prevented from being injured due to falling of a tool held in a hand of the operator. |
