sf6 switchgear quality for extra high Voltages

Switchgear:High-voltage (transmission) switchgear. Aug 04, 2015High-voltage (transmission) switchgear System considerations The transmission of high powers over long distances necessitates the use of High (HV), Extra High (EHV) or Ultra High (UHV) voltages. Historically, these voltages were classed as 72.5kV and above.
