Con BSK fire protection duct for fire encapsulation (I90/
I120)
All cable types up to a rated voltage of 1 kV can be routed.
Note!
Cables with integrated maintenance of electrical function may not be
routed in the same duct with cables for general power supply.

Con fire protection duct for maintenance of electrical
function (E30/E90)
All cable types up to a rated voltage of 1 kV can be routed. There are no
special requirements for the fire behaviour of the cables.
Note!
When dimensioning the cables, note that the electrical resistance of the
conductors in the cable is increased through heating. A larger conductor
cross-section may be required.
Comply with the maximum approved cable load (see Table 5). The
approved cable load is dependent on the classification and the mounting
version of the fire protection ducts:
