  Note
  The above-mentioned toroidal transformer is frequently-used,we can also manufacture the products by customer design. And the specification is for reference,if has the change further,please take the material object as the standard.

CHENGDE was born in 1992,specialized in Production,design and maintenance of various types of 0.55kv- 33 KV current and voltage transformer Our main Products include low voltage plastic current transformer .cast resin current transformer ,oil immersed current voltage transformers,dry type current voltage transformers and so on.
Our transformers have passed through ISO 9001 Quality Certificate.
According to customers' norms,as well as IEC,NEMA,ANSI,JEC,CNS,and related standards for design and Production. We manufactured various types of Products,and customized high frequency transformers according to customers' demands.Rigid and complete QA Systems,together with the whole line with self-examinations through layers of Quality Control from Feeding,Coil Winding,Stacked Iron Core,Core Assembly,Drying,Finish (into barrels) for Vacuum Filling Oil,Test to Shipments,which all adopted full tests.
Each individual Product has a specific manufactured number to track Production process records; each shipment attached with an inspection report.
