    For example, the first apparatus compartment 13 is shielded from the second apparatus compartment 14 by a shield 30, the bushing 22 extending through the shield 30. Alternatively, the conduit 23 extends through the shield 30. According to one embodiment, a wall element 31 is arranged between the cable compartment 12 and the the first device compartment 13, the bushing 22 extending through the wall element 31. For example, the bushing 22 is connected to the shield 30 and the wall element 31. The wall element 31 is for instance formed with holes for the conduits 24 of devices 19 arranged in the first device compartment 13. .
    Figs. 6 and 7 show an alternative embodiment of the switchgear 10, the busbar 18 being arranged in the second apparatus compartment 14. In the embodiment shown in Figs. 10 10 and 7, the vertical rail package 21 is arranged in the second apparatus compartment 14, wherein the devices 19 in both the first and second device compartments 13, 14 are connected to the vertical rail package 21 arranged in the second device compartment 14, such as by means of the supply lines 26, 29.
