These Laddle Refining Furnaces are used for supplying electrical current from transformer output i.e. low voltage stationary bus tubes or bus bars to bus bars of the electrode holding arm of the furnace. The power required for melting operation, passes through the secondary circuit thus, limiting the losses in this circuit, by way of low reactant be balanced as close as possible between the phases. This balancing of phase eliminates the transposed resistance component which reduces the hotspot problems in the electric arc furnace. Due to the presence of large fluctuations to which these cables are subjected, the permissible current density should be 4 to 5 A/mm2.
