GAS-INSULATED SWITCH DEVICE

摘要

PURPOSE: To provide a compact gas-insulated switch device which can prevent the lowering of insulation. CONSTITUTION: An insulating bushing 9A in which a projection part 11a is fixed in a flange 12 mounted on the partition wall of a box body has an insulating layer 11 formed in the periphery of a central conductor 10, and a bell-mouth part 13 is provided in the insulating layer 11 on both sides having the flange in the boundary. A grounding layer 14 is formed in the surface of the bell-mouth part 13 and at the sane time a magnetic body 15 is contained.
