Gas-insulated switchgear
GIS Switchgear for 10 kV, 12 kV and 24 kV Sealed MV Cabinets
XIYA POWER supplies sealed gas-insulated MV switchgear for 10 kV, 12 kV and 24 kV distribution projects, including JLSRM-12 RMU, XRM/SRM common-box cabinets, HXGN15-12 SF6 ring network cabinets and enclosed RMU packages. Share the SLD, module sequence, rated current, short-circuit level, SF6 tank requirement and cable interface so the cabinet option can be matched before drawings and quotation.

Fits compact cable distribution points where an enclosed, fully sealed and touchable SF6 gas chamber is required.
Voltage class
10 / 12 / 24 kVConfirm whether the project uses a 10 kV cable network, 12 kV gas-insulated RMU or 12/24 kV common-box and SF6 cabinet values.
Tank format
Sealed, common-box or enclosedSeparate stainless-steel sealed tank, common-box cabinet, SF6 ring cabinet and outdoor enclosed RMU before drawing release.
Module sequence

Rated current
125 A / 630 A / 1250 ACheck the current class by module because fuse, load-switch, vacuum-switch and breaker modules do not share one rating.
Fault level
20 / 25 / 31.5 kA classesMatch breaking current, making current, short-time withstand and peak withstand to the network calculation.
Cable and utility interface
Cable size, IP level and standardConfirm cable termination, enclosure duty, gas pressure monitoring, room limit and utility acceptance before quotation.
Site conditions
Applications and Service Conditions for Sealed MV Cabinets
Use GIS gas-insulated switchgear where compact sealed MV switching is needed and the project requires SF6, common-box or enclosed gas-insulated cabinet construction.
Cable distribution networks
Select gas-insulated cabinets for 10 kV cable engineering, ring networks and distribution terminals where sealed compact switching improves cable distribution reliability.
Secondary substations and switching stations
Use JLSRM, XRM/SRM or HXGN15 where compact secondary substations and switching stations need sealed MV switching.
Commercial, industrial and dense urban sites
Enclosed gas-insulated RMU packages fit commercial centers, industrial parks and dense urban areas where compact sealed cable distribution is required.
Transit and building power rooms
XRM/SRM and HXGN15 application text includes railways, high-rise buildings, subways, tunnels, shopping malls and airports.
Delivery controls
Drawings, Routine Tests and Packing Checks
After the gas-insulated cabinet option, voltage class and module sequence are fixed, confirm drawings, routine checks and packing method before production release. For broader sealed cabinet file review, download GIS switchgear catalog PDFs.
General arrangement drawing
Cabinet lineup, module order, sealed tank format, overall dimensions, cable compartment, foundation reference and room clearance.
Single-line and control drawings
Incoming and outgoing modules, load switch or breaker function, metering, protection, automation interface and terminal wiring.
Routine verification
Power-frequency withstand, insulation, mechanical operation, earthing operation, interlock, nameplate, gas pressure and protection-degree checks.
Packing and handling
Cabinet split, lifting point, moisture protection, SF6 sealed-tank handling note, packing marks and destination standard.
What does GIS gas-insulated switchgear mean for this cabinet range?
It refers to sealed MV distribution cabinets using SF6 gas insulation, common-box construction, SF6 ring network cabinet design or enclosed gas-insulated RMU packages. It is not a full substation GIS bay system.
How is GIS gas-insulated switchgear different from a standard RMU?
A standard RMU can be gas-insulated, solid-insulated or SF6 based. The GIS range focuses on sealed gas-insulated and SF6 cabinet construction, tank format, pressure monitoring and utility acceptance.
Which voltage classes are available for GIS gas-insulated switchgear?
Ratings cover 10 kV enclosed gas-insulated RMU applications, 12 kV JLSRM gas-insulated RMU and 12/24 kV XRM/SRM and HXGN15 cabinet values.
What should be checked before choosing C, F, V or CB modules?
Confirm the single-line diagram, load-switch duty, fuse-combination protection, vacuum-switch or breaker duty, earthing switch need, metering bay, cable termination and short-circuit level.
Which standards should be stated in the RFQ?
State the required project standard, such as IEC 62271 series or GB/T 3906 where applicable, plus any utility-specific acceptance rules. XIYA POWER should confirm the standard basis for the selected cabinet before drawing release.
What should be sent for a GIS switchgear quotation?
Send voltage class, single-line diagram, module sequence, rated current, fault level, SF6 or sealed tank requirement, cable size, termination type, metering or automation need, required standard, quantity, destination and Incoterms.
