Transformer to be Used for Wire Annealing
Magnetic Specialties shipped a 360-KVA, three-phase, 60-HZ transformer for use in wire annealing. The transformer features an extended primary winding with multiple taps to adjust the output voltage of the high-current secondary. The tap can easily be changed via the three-phase tap switch mounted to the front of the enclosure.
The delta connected secondary winding is designed for line currents up to 6,500 ARMS. The delta connection was made with large aluminum bus bars due to the high secondary current. The core and coil, along with the custom NEMA 1 enclosure, were designed using Solidworks 3D modeling.
