A gas-insulated tubular conductor arrangement is provided in which, in order to simplify the manufacture, transport and handling of the inner conductor, the support regions of the tubular inner conductor formed with the aid of columnar supports, are modified in that the inner conductor is formed, in the support region, by a short tubular intermediate piece manufactured by casting. The short tubular intermediate piece is connected at its ends with the adjoining inner conductor segments is fashioned in one piece with a respective blind-hole-type sleeve that surrounds one end of a columnar support.

Sensors positioned in power transmission systems with tubular enclosures have radio interrogation capabilities. The radio antenna assigned to a sensor is a planar antenna with a radiating element and a conductive baseplate, with the radiating element being designed as a reed that is provided in a self-supporting manner in a recess in the baseplate and is short-circuited to the baseplate at one end. This forms a quarter-wave antenna which can be tuned by using a metal resonating member with a U-shaped cross-section and can be combined with a surface-wave sensor.

A metal-clad, compressed gas-blast circuit-breaker (1) with a gas-filled housing (2) and with an interrupter unit (3), which is supported, insulated in the housing (2), has at least one insulating drive rod (26) coupled to the switching contact (20) to actuate a movable switching contact (20). This drive rod (26), which is connected to the interrupter unit (3), extends through a controlling element (5), which takes up and guides the flow of the switching gases at the time of the switching-off operation, as well as through a hollow post insulator (4) connected to the controlling element (5). The controlling element (5) allows only a portion of the switching gases to pass through in the direction of at least one drive rod (26) and diverts the remaining portion in an at least radial direction. In this manner, the pressurization of the drive rod (26) and the post insulator (4) by the switching gases is reduced. The circuit-breaker is especially suited for application in gas-insulated, metal-clad, high-voltage switching stations.
