Powerful power transformers with aluminum windings.

Abstract

Based on the calculated design studies, it is shown that the costs and total cost of active materials for transformers with a capacity of 100-160 MV * with aluminum windings compared with copper ones can be reduced by 10-12%. Such indicators were obtained with twin winding elements, transposed wire in the low voltage winding, current density 1.3 A / mm2 in the high voltage winding and cooling system D.
