Abstract
1. An arrangement for the transmission of large electrical outputs comprising large currents with small voltage differences from a transformer to an adjacent load, for example a steel melting furnace or an electrolytic bath, by means of a three-phase power line comprising conductors which have a wide cross-section in relation to their thickness, characterised in that all the conductors (10, 15, 17, 18) of the three-phase power line from the transformer windings (5, 6, 7) to the load In the region of the winding output lines (10 to 15) and also in the region of an outlet (16) through the transformer casing (9) and also in a subsequent conductor section have their broader faces respectively opposite one another with adjacent conductors (10, 15, 17, 18) mutually overlapping over their full width, and in that the width of the conductors (10, 17, 18, 15) approximately equals the height of the winding in the transformer.
