ABSTRACT:
An electrode comprises a horizontally arranged current feed which is formed by a rail of copper or has such a rail as a current conductive component. From this rail at least one current distributor branches, which is constructed of a sleeve of valve metal and a core arranged therein, and of a metal which is a good electrical conductor which is in electrical connection with the sleeve and in which preferably a contact structure is embedded which consists of valve metal and is connected to the inner surface of the sleeve by a plurality of weld positions. To the sleeve of the current distributor an active part of the electrode is mechanically and electrically conductively connected.
The essential feature of this electrode consists in that in the core of the current distributor a bar of material which is a good electrical conductor, preferably copper, engages which is connected in a mechanically and electrically conductive manner to the rail of the current feed.
