An apparatus for maintaining horizontality of a cable supporting angle of an electric power-transmission line in a transformer substation is provided to facilitate horizontal construction of the cable supporting angles at intervals in a vertical direction. An apparatus for maintaining horizontality of a cable supporting angle(26) of an electric power-transmission line in a transformer substation includes a vertical fixed frame(10), front and rear variable supports(20,20a), and a stopper(30). The vertical fixed frame is vertically fixed to a wall of a common-use channel. The front and rear variable supports are axis-fixed to the vertical fixed frame and maintain the horizontality of the supporting angle through a horizontal display window(23). The stopper persistently maintains horizontality of the front and rear variable supports. |
