Gas Insulated Switchgear process for Maintenance

Gas Insulated Switchgear process for Maintenance

Gas-insulated switchgear is the compact metal encapsulated switchgear, which has high-voltage components such as circuit-breakers and disconnectors, which can be safely operated in confined spaces. It is flexible in design, maintenance-free substation, and occupies very less space compared to conventional substations.
