Gas insulated switchgear is used in power systems, to control, protect, and isolate electrical equipment, such as circuit breakers, voltage and current transformers, disconnectors and earthing switches, control & protection device, and other supporting elements such as SF6 bushings and cable terminations among others. These equipment are enclosed in a metal chamber with SF6 gas insulation that has high dielectric properties and two to three times the insulating ability of air at the same pressure.

Gas-insulated high-voltage switchgear (GIS) is a compact metal encapsulated switchgear consisting of high-voltage components such as circuit-breakers and disconnectors, which can be safely operated in confined spaces. GIS is used where space is limited, for example, extensions, in city buildings, on roofs, on offshore platforms, industrial plants and hydro power plants. WE has always been and continues to drive innovation in GIS technology in ratings, operations, switching technology, smart control and supervision, and compactness. As a result, OUR GIS offers outstanding reliability, operational safety and environmental compatibility. It provides a complete range of products for all ratings and applications from 12 kV to 24kV matching current and future requirements for modern switchgears.
