Gas Insulated Switchgear GIS for Primary Distribution
What is primary gas-insulated switchgear (GIS)?
Medium voltage switchgear for primary distribution up to 52 kV using gas as insulation, enclosed in a metal enclosure and including high-voltage components like circuit breakers and disconnectors.
What are the benefits of primary GIS?
- Space efficiency: Compact for use where space is limited, with applications from transformer substations to primary power supplies.
- Reliability and longevity: The sealed design withstands harsh environments and offers long life with minimal maintenance.
- Enhanced safety: Internal arc resistance and robust construction, including safety devices to protect operators and equipment from overloads and short circuits.
What are key features of primary GIS?
Compact size, high reliability, and strong performance.
Where is it used?
GIS is used in mining, petrochemical, oil and gas, renewables, container substations, railways, wind power, and critical infrastructure.
