DUO CORE
This is a low loss price competitive core with very easy assembly. It is used for core-type, single leg and shell-type, single and 3-phase Distribution and General Purpose Transformers. Annealed DUO cores with one lamination per overlap will have the lowest core loss. After assembly into windings TIG welding of the last lamination and wedging is recommended.

Process single strip up to 410mm (16") or process 2 strips up to 185mm (8") each.
