5. Structure Introduction
        FT16(FZN)Load switch structure as shown in FIG. There are blades, insulators, wall bushing, vacuum interrupter device, the operating mechanism, undercarriage and other components. FT16-40.5R (FZRN-40.5) combination units divided two parts, the right part of the fuse, the left portion of the isolation switch, two parts separated by a metal undercarriage, and through wall bushing load switch causes the fusion and the isolation switch electrical connection.
