Abstract: A connecting unit containing a four-segment inner conductor connection in an enclosure provided with two partitioning insulators and a installation opening, is used to provide easy mechanical access to an inner conductor of two partitioned sections of a gas-insulated, tubular conductor system, with one conductor segment of the inner conductor connection detachably connected in a shape of a claw to adjacent connector segments.

Abstract: Attachment points of an internal conductor in single-phase gas-insulated power transmission systems with tubular external and internal conductors are designed to have high dielectric strength and are of simple design, an end piece (6) of internal conductor is axially secured in a post insulator two head pieces (61, 71) radially and axially secured in a feed-through bore of the post insulator and axially connected to one another. The head pieces are configured as control electrodes. One head-shaped piece is also used as a plug contact with the adjacent internal conductor section.
