Gas-insulated switchgear (GIS) is a system in which high-voltage components such as busbars, circuit breakers, disconnect switches, transformers, power cables, etc., are sealed within a shell filled with low-pressure (typically 0.02-0.05 MPa) gas. It offers the following advantages:
utilizing SF6 gas insulation significantly reduces the volume and footprint of the GIS, promoting compactness.
Since high-voltage components are enclosed within the shell filled with SF6 gas or other gases, they are not influenced by external environmental conditions.
The use of maintenance-free vacuum switches greatly enhances reliability.
Gas-insulated switchgear can be employed in extremely harsh environmental conditions. These include regions with significant temperature variations and high humidity (e.g., tropical areas), high-temperature and low-temperature areas (e.g., desert regions and polar areas), places with natural substances (e.g., coastal salt spray, industrial dust) or chemical corrosive agents (e.g., chemical plants, refineries), seismic zones, areas with vibration, high-altitude regions, and places with restricted installation conditions.
