APPLICATION & DUTY
Where XGN17-40.5 fits
XGN17-40.5 is fixed indoor metal-enclosed switchgear for receiving and distributing power in 35 kV networks. It is arranged around a single-bus or bus-bypass scheme. Its fixed construction and installation envelope distinguish it from withdrawable-truck equipment.
APPLICATION / 02
Substation distribution
For feeder schemes using a single bus or a specified bypass arrangement.
PRODUCT ENGINEERING
Construction & operating functions
DETAIL / 01
Fixed primary-equipment arrangement
The primary devices remain in a fixed cabinet arrangement. Access, maintenance space and isolation requirements should therefore be considered in the substation layout.
DETAIL / 02
Bus-scheme selection
The design scope includes single-bus and bus-bypass systems. Incoming, outgoing and bypass functions should be shown clearly on the single-line diagram.
DETAIL / 03
Enclosure protection
The stated enclosure class is IP2X. Room environment and access arrangements should be selected around the actual indoor installation.
DETAIL / 04
Switching and withstand duty
The series information lists current and fault-duty alternatives. Select a complete matched rating instead of combining independent maximum figures.
