- High Voltage Gas Insulated Switchgear is used in 35kV–220kV high-voltage power systems where equipment footprint and environmental isolation are important project considerations.
- Typical applications include urban underground substations, hydropower stations, data centers, and compact high-voltage substations.
- The equipment is relevant where a conventional air-insulated arrangement would require more installation space.

Sealed Insulation Structure:
- SF6 gas is used as the insulating medium.
- The main live parts are enclosed inside a fully sealed metal structure, reducing direct exposure of the internal insulation system to dust and moisture.
- The enclosed arrangement also supports compact equipment placement within the confirmed high-voltage range.
Electrical Selection Range:
- Rated voltage covers 35kV to 220kV, while rated current ranges from 630A to 4000A.
- Confirmed short-circuit breaking capacity is 20–50kA.
- System voltage, current, and required breaking capacity should be checked together against the project electrical design before a final configuration is released.
Drawing-Based Configuration:
- Custom production may be discussed according to rated voltage, rated current, short-circuit breaking capacity, and customer technical drawings.
- OEM/ODM service is available after the relevant authorization conditions are completed.
- For High Voltage Gas Insulated Switchgear, technical parameters and drawings are confirmed before customized production begins.
Release Inspection and Export Packing:
- Raw materials are inspected on arrival, with additional checks carried out through multiple production stages.
- Finished equipment receives electrical performance testing, followed by 100% electrical performance inspection before packing.
- Buyers may arrange third-party factory inspection before shipment.
- Export equipment receives rust-prevention treatment according to the product condition and is packed in reinforced solid-wood cases for long-distance transportation.
- Customized equipment generally requires 20–35 working days according to confirmed technical requirements.
- Inquiry information should include system voltage, rated current, breaking capacity, quantity, site conditions, and project drawings.
