Abstract
In this system, the electrode supporting arms (2) formed of a closed, hollow, liquid cooled profile for an electric furnace are provided with a vertical member (14) having the same type profile structure at whose lower end the electrode (17) is exchangeably fastened, preferably by means of a clamping device (15). For better current transfer, the supporting arms (2) are in part made of a two-component compound material, preferably to correspond to their current charges.
