Utility Model Patent Name: High-voltage coiling of 35KV amorphous oil-immersed transformer

(1)  Patent Number: 201120150449.8

(2)  Date of application: 05/12/2011.

(3)  Expiry date: 05/12/2021

(4)  Patent abstract

      The patent applies to high voltage coiling of a type of transformer, typically high-voltage coiling of 35KV amorphous oil-immersed transformers. It has the advantages of small size and cost savings, materially lowering the layer insulation voltage to improve the vertical insulation level and insulation density of coiling and increase the useful life of transformers.

China Power is one of the major producers of amorphous alloy cores for amorphous transformers in China.
