ABSTRACT:
An arc furnace particularly for smelting of steel comprises three electrodes arranged symmetrically on a circle and connected to the phase by contact pads mounted on horizontal carrier arms.
For optimizing the current loading of the contact pads and for minimising reactive losses of the arrangement, the contact pads are arranged centrosymmetrically within the electrode pitch circle.
