Information : Transformer Curing
To make low-noise transformers, the windings must be kept tight. During the curing process, the metal windings expand and gaps are introduced which cause the transformers to be noisy. MagneTek Defense Systems (MDS) eliminated this problem by applying a DC voltage to the transformer during the curing process. The magnetic field created by the DC voltage pulls the windings together and holds them in place until the curing cycle is completed. This practice has allowed MDS to construct significantly lower noise transformers.
