Abstract
Bus bars for connecting arc furnance electrodes to a transformer include pairs of flat, rectangular, hollow, conductive members having side surfaces substantially greater in length than the end surfaces. One side surfaces of the bus bar of each pair are disposed in a parallel, closely proximate relation with respect to the other and a sheet of insulating material disposed between said surfaces. The bus bars of each pair are connected to transformer terminals having different polarities. The bus bar pairs are arranged in a closely spaced parallel relation.
