摘要： A coaxial bus and bus system for electric furnaces which significantly reduces and minimizes heating and losses due to magnetic induction effects are characterized by a concentric tubular bus stem connected at one end to a transformer and branching at the other end to be connected to the furnace. The bus stem includes concentric tubular conductors which are connected at such one end to the transformer by respective diametrically opposed terminal lugs. At such other end, bus branches each including a conductive cross bar and a flexible feeder are respectively connected to the tubular conductors and form a yoke between which the furnace heating element or elements may be connected. The feeders are adjustably secured both pivotally to and longitudinally along their respective cross bars and each includes a plurality of stacked conductive leaves which are pressure welded together and to contact and reinforcing plates at their ends. Provision also is made for air or water cooling by means of coolant passages in the terminal lugs, bus stem and bus branches.
