Abstract: A current conductor for an electrical device including an electrically conducting central section having a first side and a second side. The central section is configured to receive at least one inserted electrical component. Two electrical conducting shield sections are each disposed on one of the first side and the side and configured to shield against an electric field. The shield sections cover the central section and the at least one inserted electrical component.

Abstract: The invention relates to a post insulator (4) whose surface (41, 51) is geometrically configured, in at least one area (4a) between an inner conductor (2) and encapsulation (3) for a gas-insulated switchgear assembly (1) such that surface discharge paths (6b) are provided between the inner conductor (2) and the encapsulation (3) and have a subsection in the opposite direction to the bridging direction (7). In consequence, surface discharges (6a) can be diverted in the opposite direction to an original propagation direction (7), and come to rest by self-blocking. Exemplary embodiments relate to: an indentation (4b) which is concave and is open toward the inner conductor (2) and/or toward the encapsulation (3) and is formed between a cup shaped barrier (5) and the base body (40) of the post insulator (4); diversion of surface discharges (6a) through up to 180° for efficient self blocking; and adhesive bonding (45) of the barrier (5) on a conventional post insulator (4).

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).
