  • Gas-tight metal-clad bushing
    Patent number: 6747207
    Abstract: A bushing for high-voltage and medium-voltage gas-insulated metal-clad electrical switchgear includes a substantially cylindrical metal jacket surrounding a conductive busbar. It also includes a conductive material annular member disposed around the jacket and a cap surrounding the jacket at a distance and adapted to define with the jacket a closed space delimited at one end by the annular member, which is adapted to be sacrificed by being partly melted if an internal arc pierces the jacket and reaches it. This kind of bushing prevents molten metal and hot gases from spraying out following an internal arc.
