1.9.4. Vertical wireway
The vertical wireway is formed by the segregation walls on
either side of the device and is directly connected to the
top and bottom with the horizontal wireways.

1.10. Seismic structure Frame
When a seismic structure is required there is a specific
frame available. Basically, in this frame the transverse
channels are required in cold roll steel without painting or
plating. This frame allow to have the structure welded
when is installed.
Switchgear frame for seismic structure
This frame includes stainless steel parts also in some cases
and purpose is to minimize generation of magnetic fields
in the structure.
When a seismic structure is required a specific sub-frame
is available. Basically additional plates are included to give
stiffness to the structure.
This assembly includes also two side walls which are
mounted in the device compartment; these are used to
segregate the device compartment in a single unit lineup
or multi-section lineup. These side walls are manufactured
in sheet metal 2.0 mm thickness.
