Description

technical field [0001] The invention belongs to the field of power materials, and in particular relates to a transformer shell material and a preparation method thereof. Background technique [0002] The transformer shell is mainly used for the safety protection of the operation transformer site. Avoid accidents caused by foreign objects such as small animals and rainwater entering the transformer, avoid damage to the transformer caused by corrosion, and the transformer can protect personal safety. In the existing technology, there are few researches on the transformer shell, but the safety hazards caused by the transformer shell are more and more. In order to ensure the safety of people's production and life, we need to study a kind of transformer with good corrosion resistance, good electromagnetic radiation shielding, Transformer housing with high mechanical strength. Contents of the invention [0003] In order to solve the problems of poor corrosion resistance, poor ...
