Whether in design, manufacturing methods   or materials the cores of Farady transformers represent the latest state of technology. The   silicon alloyed electric sheet steel used is grain-oriented, cold-rolled and insulated on both sides, guaranteeing low losses and noise and these values are even improved by laser treatment. Numerically controlled cutting machines provide for careful treatment in the cutting process in order to avoid mechanical tension in the core and thus unwanted properties right from the beginning. Standard use of step-lap cutting additionally minimizes losses and noise.
