PURPOSE:To improve the efficiency of mounting work and the accuracy of mounting by attaching upper and lower attachment panels, on which various types of bushing and apparatus are mounted, to one surface of a framework constituting a box in such a way that the attachment plates serve as a side panel of the box. CONSTITUTION:Components such as cable bushings 14, grounding bushings 16, and an earth system 18 are previously mounted on an upper attachment panel 13. Bus bushings 20 and bushings 21 having a built-in CT are also previously mounted on a lower attachment panel 19. The upper and lower panels 13 and 19 are mounted to one surface of a framework 12 that constitutes a box 11, whereby one side panel of the box 11 is formed. Thereby, the accuracy of mounting as well as the efficiency of work of mounting various types of member are improved. |
