FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, in particular to the design of the transformer core. Transformer core is formed by layer-by-layer application of at least two types of textured sheets of electrical steel, which differ in magnitude of magnetostriction by 2 × 10-7 or more at magnetization from 0 T to 1.7 T.
EFFECT: technical result is reduction of core vibration and noise level of transformer.
