Toroidal/annular/ring transformer 2 million PCS,
EI transformer 3 million PCS annually;
Three Phase Transformer 50000pcs
Others 100000 pcs
About 200 workers, 5 technicians, 2 senior engineers
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.
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'.
The certificate of our transformer has CE CQC RoHs UL
The above-mentioned single phase 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.
