    Aug 01, 1982The development and testing of the main components of a metal clad SF6-insulated switch gear for dc voltages up to 600 kV are described. The technical requirements of the components were derived from the design of a switchgear arrangement. The switchgear was tested, proving that switching requirments were met.

  • HazardEx - Crowcon F-Gas Detector for SF6 – Ideal for

    The SF6 used in GIS is a much better insulator and spark quenching gas than air, and as a result, switchgear with SF6 has become increasingly popular and cost effective during the last 20 years. Indeed, when it comes to high-voltage switchgear (above 52 kV), there are, currently, few viable alternatives to SF6 in its switching role.
