<p>PROBLEM TO BE SOLVED: To provide a gas-insulated switchgear equipped with a spacer the electric field relieving ability which deteriorates little and which has high mechanical strength. SOLUTION: Conductors 3 and 3 are supported in a metallic container 2 in insulated states by a spacer 4 carrying annular shield electrodes 12 and 13, respectively arranged on the outer peripheral edge section of a conical insulator 11 and on the peripheral surface of a conductor 6, with the conductor 6 penetrated through at the center of the insulator 11. The electrodes 12 and 13 are made of epoxy resin compositions, having resistances properties against decomposing SF6 gas and relax strong electric fields generated in the vicinities of the fixing section between the container 2 and spacer 4 and the conductor 6.</p> |
