Before fixing the panels side by side (according the general drawings) bushings 29 (12÷24 kV) must
be fixed (for switchgear with busbar barriers only; refer to the table on page 13).

5.4.2 Bushing of 24 kV panels
Assembly procedure for bushings – main (upper) busbar system:
• Insert bushing 29 for the lower busbar into bushing plate 28 from the right side, and the middle and
upper one from the left side (figure ).
Lower bus-tie system:
• Insert bushing 29 for the lower rear bus-tie into bushing plate 28.2 from the right side in contrast to
the procedure for the other two bushings (see Figure 8).
