01

Voltage class

3.6/7.2/10/12/40.5 kV

XGN2 fits 3.6/7.2/12 kV work, XGN66 covers compact 10/12 kV duty and XGN17 covers 40.5 kV indoor HV rooms.

02

Rated current

630 A to 3150 A

For higher current classes, check XGN2. XGN66 covers compact 630 A duty and XGN17 covers 40.5 kV projects up to 2000 A.

03

Fault level

20/25/31.5/40 kA classes

Match breaking current, making current, peak withstand and 4 s thermal current to the protection study.

04

Fixed cabinet layout

Box-type indoor cabinet

Confirm that fixed cabinet maintenance fits the room before choosing XGN instead of KYN28 withdrawable switchgear.

05

Busbar structure

Single busbar or bypass

XGN2 includes single busbar section and single busbar with bypass structures. Confirm the busbar plan before drawing release.

06

Room and cable interface

Dimensions, trench and access

Check cabinet width, depth, height, cable entry, foundation reference and operation aisle with the project room layout.

Site conditions

XGN Fixed-Type Switchgear Application and Installation Conditions

Install XGN fixed-type switchgear in indoor MV or HV rooms where a fixed AC box-type cabinet suits the operating and maintenance plan.

01

Power plants and stations

Select XGN17, XGN2 or XGN66 where fixed indoor switchgear is specified for plant or station receiving and distribution.

02

Substations and distribution rooms

Fit this cabinet type to substation and distribution-room duty after confirming voltage class, current duty and operation aisle.

03

Industrial and commercial buildings

Apply fixed cabinets in indoor building power rooms where fixed maintenance access is acceptable.

04

Box-type transformer substations

XGN66-12 fits compact 10/12 kV fixed switchgear packages for box-type transformer substations.

Delivery controls

XGN Fixed-Type Switchgear Drawings, Routine Tests and Packing

04

Packing and handling

Cabinet split, lifting point, moisture protection, packing marks, pallet or wooden case and destination standard.

When should XGN be selected instead of KYN28?

Select XGN when a fixed AC box-type cabinet fits the room, maintenance method and switching duty. Select KYN28 when the project needs withdrawable VCB truck operation.

Can XGN cover both 12 kV and 40.5 kV projects?

Yes. XGN2 and XGN66 support 12 kV class selection, while XGN17 supports 40.5 kV fixed high-voltage switchgear. Keep the selected model tied to the project voltage and fault level.

What is the difference between XGN2 and XGN66?

XGN2 covers 3.6/7.2/12 kV with 630-3150 A current classes and busbar structure options. XGN66 is a compact 10/12 kV fixed cabinet with 630 A duty and 31.5 kA short-circuit breaking current.

Is XGN suitable for outdoor installation?

The supplied XGN17, XGN2 and XGN66 data describes indoor AC box-type switchgear. Outdoor installations should be quoted as a separate enclosure or substation package.

Which details are needed before XIYA POWER confirms the XGN model?

Send the single-line diagram, voltage class, rated current, breaking current, short-time withstand current, cabinet function, CT/PT requirements, metering, protection, cable entry, room layout, quantity, destination standard and Incoterms.
