    A. 1. Installation: Horizontal (non-conventional-type base plate), sunk, side type, and bridge. 2.Application: Especially low-hum and low-dispersing construction Low-level of induction High-grade design casing possible Statically shield winding and magnetical shield winding optional . 3.Equipment: Over 50 sets toroidal/annular/ ring coil winding machines, 3 EI type transformer lines, 2 sets of vacuum annealing furnaces, A set of nitrogen and hydrogen production equipment. 4.Warning Under no circumstances should both ends of the fixing bolt simultaneously contact the metal chassis or framework as this would create a potentially dangerous 'shorted-turn'. 5.Certificate The certificate of our transformer has CE CQC RoHs UL 6.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.   We can manufacture High Frequency Transformers,EI Power Transformers.Below is our mainly products with much advantages in our market:
