Abstract: PROBLEM TO BE SOLVED: To provide a supporting insulator of a gas-insulated switchgear which is constructed so as to make a discharge path between the inner conductor (2) and capsule (3) of the switchgear have a partial section having a direction opposite to a bridging direction. SOLUTION: Surfaces (41 and 51) of a supporting insulator (4) have recessed parts (4b) having openings having concave shapes facing a component (2) or a supporter (3) in a region between the component (2) and the supporter (3).

Abstract: PROBLEM TO BE SOLVED: To provide a disconnector which has a high dielectric strength, and can be simply and inexpensively manufactured in small size. SOLUTION: The disconnector provides two insulated contacts (2) disposed in a conductive capsule container (1) filled with essentially insulating gas, and an insulated finger (3) movable between the insulated contacts. An insulating coating (7) is formed in the capsule container and has a protrusion (8) protruding toward the inner. The insulating coating prevents a spark generated in the disconnector from flashing over the capsule container (1) when the disconnector is opened. Another protrusion (9) prevents the spark from propagating toward the insulated contacts (2).

Abstract: The disconnector essentially comprises two isolating contacts (2), which are arranged in electrically conductive encapsulation (1) filled with insulating gas, and an isolating contact finger (3) arranged such that it can be moved between them. An insulation coating (7) is applied to the inside of the encapsulation (1) and has projections (8) pointing inward.The insulation coating prevents a disconnector spark (5), whose production cannot be avoided when the disconnector is opened, from flashing over onto the encapsulation (1). Furthermore, additional projections (9) prevent the spark from propagating in the direction of the isolating contacts (2).

Abstract: The electrical insulator has an insulator body 3 which is fitted between an electrical conductor 1 and a grounded holder 2 . The surface of the insulator is at least partially formed by a protective body 6 . The material of the protective body has a low dielectric constant in comparison to that of the material of the insulator body 3 . The protective body 6 prevents an electrically conductive particle 12 from coming to rest directly on the surface of the insulator body 3 , in particular in the region of the triple points T, or causing a considerable increase in the field due to immediate proximity to the insulator body 3. The breakdown voltage of a gas-insulated system which contains such insulators provided with a protective body is increased. Gas-insulated systems can thus be made more compactly and more cheaply, and their life can be extended.

Abstract: The supporting insulator has an insulating body (3) and at least one protective body (6) at least partly forming the surface of the insulator. The protective body contains a material with a lower dielectric constant than the material of the insulating body and/or has a structure with a lower mean dielectric constant than the material of the insulating body.

Abstract: Gas insulated conductor cable (1) has an inner cable (4) for a high voltage current and a mantle pipe (2) filled with an insulation gas. Supporting insulators (3) hold the inner conductor cable (4) centrally from the inner surfaces of the mantle. The mantle pipe (2) is of a material with distortion for a recess to be formed in the mantle surface, to be filled by a collar or covered by an elastomer hose (9) for the insulator support points.
