  • Three abnormal situations leading to an uncontrolled release

    Abnormal leakage. The method of risk assessment is similar to that used in section “leakage from SF6 – filled equipment” which deals with normal leakage. Internal fault. An internal fault can develop when an arc is formed abnormally between the main conductors of an item of switchgear, or between a main conductor and an earthed conducting part. External fire. Fires in outdoor installations rarely cause problems because of the relative absence of flammable material in the vicinity of the switchgear.

  • Gas-insulated Switchgear Market worth $26.5 billion by 2025

    SF6-filled gas-insulated switchgears are preferred over air-insulated switchgears where space is a constraint because air-insulated switchgears require meters of air as an insulation medium to do what SF6-filled switchgears can do in centimeters. Therefore, SF6-filled gas-insulated switchgears can be 10 times smaller than air-insulated switchgears.
