110kV-252kV Hybrid Gas-Insulated Switchgear (H-GIS)

Product description

Product Overview
The Hybrid Gas-Insulated Switchgear (H-GIS) is a versatile and innovative solution designed to bridge the gap between traditional Air-Insulated Switchgear (AIS) and full Gas-Insulated Switchgear (GIS). By integrating core switching components into a gas-insulated enclosure while utilizing air-insulated busbars, H-GIS provides a highly adaptable platform for power system upgrades and substation expansions.
Key Features
Retrofit Optimization: Specifically engineered for the modernization of existing substations, allowing for the replacement of aging AIS equipment with compact, high-performance gas-insulated modules without rebuilding the entire facility.
Hybrid Technology Advantages: Combines the superior reliability and environmental protection of GIS at the component level with the accessibility and lower busbar costs of AIS, striking the perfect balance between performance and investment.
Modular Integration: Featuring a flexible Modular integration approach, the H-GIS can be customized to include circuit breakers, disconnectors, and earthing switches within a single SF6-insulated housing tailored to specific site layouts.
Exceptional Cost-effectiveness: Offers significant savings in capital expenditure compared to a full GIS installation, as it utilizes existing outdoor busbar structures while providing the compact footprint and reduced maintenance of gas-insulated technology.
Rapid On-site Implementation: The factory-tested, compact modules allow for Rapid on-site assembly, drastically minimizing the downtime required for substation brownfield projects.
Technical Specification

Parameter	Specification
Rated Voltage	110kV - 252kV
Rated Current	1250A / 2000A / 3150A
Rated Breaking Current	31.5kA / 40kA
Annual Gas Leakage Rate	≤0.1%
Mechanical Endurance	10,000 Operations (M2 Class)

Application Environment
Substation Retrofitting: The primary choice for upgrading old 110kV/220kV AIS substations where space for expansion is limited but a full GIS conversion is not budget-justified.
Flexible Capacity Expansion: Ideal for adding new feeders to existing power hubs where the original switchyard footprint cannot accommodate traditional equipment.
Industrial Site Upgrades: Provides a reliable and compact switching solution for factories or mining sites needing to increase power capacity within fixed infrastructure constraints.
Extreme Weather Protection: Protects critical switching elements from salt spray or heavy industrial pollution while maintaining a cost-effective outdoor busbar arrangement.

FAQ
1. How does H-GIS help in "Retrofit" projects?
H-GIS allows you to replace a large, high-maintenance AIS breaker and its surrounding disconnectors with one single, compact H-GIS module. This frees up space in the existing yard for other equipment or capacity increases.
2. Is H-GIS as reliable as a full GIS?
For the core switching functions, yes. The circuit breakers and disconnectors are housed in the same hermetically sealed SF6 environment as a full GIS, protecting them from environmental wear and ensuring an annual leakage rate of $\le$ 0.1%.
3. Why is H-GIS considered more "Cost-effective"?
Full GIS requires expensive gas-insulated busbars and housing for the entire station. H-GIS only insulates the core "moving parts," allowing you to use standard, inexpensive air-insulated conductors for the rest of the yard.
4. Can H-GIS modules be expanded in the future?
Yes. Due to the Modular integration design, additional modules can be added to the existing H-GIS lineup as your power demands grow, making it a future-proof investment.
