Circle – C transformers are designed to meet and surpass the requirements of the relevant Australian Standards. Materials and manufacturing procedures utilised, provide the best performance for the most difficult duties and environments. Only High grade electrical steel is used ensuring low iron losses and all windings are manufactured from high conductivity PEI2 insulated circular or rectangular copper conductors. Transformers are manufactured using materials for Class A (105°c), Class B (130°c), Class F (155°c) or Class H (180°c) applications.
