Abstract:
A gas-permeable power transmission system, comprising:a tubular internal conductor including internal conductor sections, the internal conductor sections connected to one another via a plug-and-socket connection;a tubular external conductor arranged concentrically with the tubular internal conductor and including external conductor sections;insulating spacers supporting the tubular internal conductor in the tubular external conductor;a disk-shaped post insulator axially securing one end of a first one of the internal conductor sections in the tubular external conductor, the disk-shaped post insulator having a central feed-through bore and being axially secured to the tubular external conductor and tightly surrounding the tubular internal conductor in an area of the central feed-through bore, the central feed-through bore having a diameter which is smaller than an outer diameter of the tubular internal conductor, the one end of the first one of the internal conductor sections including an end piece in an area of the disk-shaped post insulator, the end piece firmly connected to a second one of the internal conductor sections, the end piece including a cylindrical plug contact of a plug-and-socket connector, a hollow cylindrical sliding contact being attached to an end of the second one of the internal conductor sections, a socket of the plug-and-socket connector being formed by the end of the second one of the internal conductor sections and the hollow cylindrical sliding contact, the disk-shaped post insulator having short annular flanges, the short annular flanges positioned on first and second sides of the disk-shaped post insulator and being in the area of the central feed-through bore, the end piece including head-shaped pieces which are friction-locked to one another through the central feed-through bore, the head-shaped pieces radially extending beyond the central feed-through bore and the short annular flanges, each of the head-shaped pieces being in contact with the annular flanges and being configured as a first control electrode with a nose-shaped cross section projection, each nose-shaped cross section projection engaging a respective one of the annular flanges from behind, a first one of the head-shaped pieces being directly and firmly connected to a tubular portion of the first one of the internal conductor sections, a second one of the head-shaped pieces including a tubular extension forming the cylindrical plug contact.
