摘要： The gas-insulated line comprises a conductor (1A) disposed inside a case (3A) filled with a dielectric gas under pressure. A power capacitor (5) is electrically connected to the conductor while being disposed inside a compartment (3P) secured to the case (3A) and filled with a dielectric gas under pressure. The dielectric gas present in the compartment (3P) provides electrical insulation for the compartment relative to the power capacitor (5). In this way, electrical insulation of the gas-insulated line between the conductor (1A) and the case (3A) is maintained inside the compartment (3P) in which the power capacitor (5) and the conductor (1A) are electrically interconnected. This results in the gas-insulated line of the invention retaining small bulk and the ability to be used on the ground or buried.
