Gas Insulated Ring Main Units We Manufacture
XGN15-12 inflatable gas insulated ring main units for 12 kV loop networks and compact substations – compact, sealed and maintenance-free.
What Is High Voltage Gas Insulated Switchgear?
Gas insulated switchgear (GIS) seals the live components in an insulating gas, allowing a much smaller footprint than air-insulated designs. The XGN15-12 RMU is the standard GIS format for distribution.
Gas insulated RMUs suit urban networks, compact substations and indoor installations where space is at a premium and maintenance access is limited.
- Compact footprint – sealed gas insulation saves space.
- Maintenance-free – sealed design reduces service work.
- 12 kV class – standard for distribution RMUs.
- 50,000m²工場 – in-house assembly and testing.
- 350人以上の従業員 – エンジニアリング、品質、輸出チーム。.
- OEM / ODM & 卸売 – カスタムブランディング、パッケージング、ボリューム供給。.
Main Types of Gas Insulated Switchgear
We manufacture two GIS configurations:
Ring main unit
Compact 2-3 function units for loop networks.
Transformer feeder unit
GIS with transformer protection functions.

Gas Insulated vs Air Insulated Switchgear
Gas insulated switchgear is far more compact and virtually maintenance-free, at higher cost; air insulated designs are cheaper but need much more space and regular maintenance.
For urban and indoor sites, the space saving of GIS usually justifies the cost.
Choosing a Gas Insulated Switchgear Manufacturer
Verify pressure sealing, type test evidence and gas handling compliance – the factors that define GIS reliability.
