Gas Insulated Switchgear monitorand record for extra high Voltages

An HV switchgear is designed to handle between 69 kV and 230 kV. Thanks to their high resistance, their life cycle costs are fundamentally low and an HV switchgear can easily outlast the other types even in lower voltage systems. Extra High and Ultra High Switchgears are sold as well, though ultimately, they can be counted as part
