PROBLEM TO BE SOLVED: To provide a conductive glazed bushing with a center clamp structure capable of sufficiently exerting a stain-resistant property and simply checking a state of insulation deterioration of an electronic apparatus using the bushing. SOLUTION: The conductive glazed bushing with a center clamp structure, compressed by tension of a central pipe 9, is formed by making an outdoor-side insulator tube serve as the conductive glazed insulation tube 3, and interposing a gasket 7 between an upper end face of the conductive glazed bushing and a high-voltage side metal fitting 5, and between the lower face of the bushing and a grounding side metal fitting 1. Conductive metal fittings 16, 17 are conductively fixed to the upper and lower end parts of the conductive glazed insulation tube 3 by an adhesive material like conductive cement. The conductive metal fittings 16, 17 and high voltage-side metal fitting 5, and also the conductive metal fittings and the grounding side metal fitting 1 are electrically connected by flexible conductors 19, 20 equipped with removable end parts. Insulation resistance or the like can be measured by simply removing the flexible conductors 19, 20 at the time of checking. COPYRIGHT: (C)2006,JPO&NCIPI
