<p>PURPOSE: To prevent the movement of foreign metal matter to a gas-insulation space, to allow the influence of the matter to scarcely affect the dielectric breakdown characteristics of the space in which the matter exists and to enhance the insulation reliability with a small size. CONSTITUTION: A gas-insulated switch has a high-voltage conductor 7 for conducting in a metal vessel 8 for sealing insulation gas therein, and an insulating structure member 12 for insulating the conductor 7 from the vessel 8, and comprises a fine powder layer 15 provided around the conductor 7.</p> |
