  • Solid insulation switchgear for space savings and safety - EE

    Gas-insulated switchgear (GIS) uses less space but there are problems with the gas used. SF 6 is regarded as a greenhouse gas and there is a move away from the use of SF 6 in switchgear. SF 6 is a synthetic compound and does not normally occur in nature. It is gaseous at room temperature and is heavier than air.

  • Panel discussion: The pros and cons of using SF6 gas in

    The term GIS (gas insulated switchgear) in MV is commonly used also in hybrid solutions, which are partially SF6 based switchgear systems. It is used where, for example, the busbars are solid dielectric and only the circuit breaker, disconnectors and earthing switch are in SF 6 gas. GIS is today a proven technology with more than 30 years of experience, resulting in it gaining greater investor trust and economic justification.
