Abstract: A current pass-through arrangement for a rodlike electrode passing substantially perpendicularly through a hot wall of a container features an inner seal and an outer seal, with the outer seal located at a substantially cooler position than the hot wall. Preferably, a portion of the electrode is tightly fitted into a cylindrical bushing of electrically insulating material. The electrode projects out of this bushing, at least at the container-adjacent end. In turn, the bushing is tightly fitted into a wall element (4) having a smaller-diameter end and a larger-diameter end which is sealed into the container wall. The wall element (4) and the electrode centered within it define an annular space which is at least partly filled with sealing material (5). According to a further embodiment, the electrode also projects from the container-remote end of the bushing (3).
