Abstract:
    A gas-insulated equipment such as a gas-insulated switchgear provided according to the invention can efficiently improve dielectric strength of an entire electrode system considering electric field distribution of the electrodes and conductors and improving insulation coordination so that miniaturization of the entire device can be achieved. The gas-insulated switchgear includes insulating gas 7 sealed within an earth metal container 1 and an insulating spacer 3 insulating and supporting high-voltage receiving portions. Surfaces of shielding electrodes 6 having a larger diameter than that of high-voltage conductors 2 are covered with thick dielectric coatings 8, and surfaces of the high-voltage conductors 2 are covered with thin dielectric coatings 9.
