<p>PURPOSE:To simplify the makeup of a bus supporting structural steel and to compact the site area, by constituting the bus supporting structural steel as having bus supporting arms as in the transmission steel tower. CONSTITUTION:On both sides of a bus supporting structural steel provided are bus supporting arms 4U, 4V and 4W each for three-phase. The supporting arm 4U at the topmost section is constituted shorter than the other supporting arms 4V and 4W. At the supporting arms 4U, 4V and 4W supported are buses 6U, 6V and 6W with supporting insulators 5U, 5V and 5W respectively. The bus 6U trails a connecting bus 7U, which is connected to a bushing 11U after supported with supporting insulators 35U. Buses 6V and 6W are connected to bushings 10V & 11V and to 10W & 11W respectively. The bus supporting structural steel is thereby so simplified that the insulation area can be compacted.</p> |
