As we all know, the construction, rated power, voltage level and scope of the application are all key factors that determine the transformer’s design. The transformer is mainly composed of winding and magnetic core. The winding is usually made of electrolytic copper of a high conductivity and insulation material. The magnetic core is usually made of laminations of non-ageing, cold-rolled, grain-oriented, silicon steel of high permeability without burrs.

The products meet the international standards of IEC 60076 and can be designed, manufactured and tested according to customers’ requirements. We can also produce transformers with special requirements including low loss, low noise and fireproof etc.

We now have vacuum casting production line made by the international advanced level of German company HEDRICH and dry transformers technology software of Austrian ENCO Company. 

There are international advanced level Joe grid line, domestic advanced foil type winding machine, more than 30 sets all kinds of equipment, partial discharge detector, lightning impulse generator, induction voltage regulator and other test equipment. The annual production capacity is up to 7 million kVA.

The various series transformer products have achieved ISO9001:2015 quality management system certification, ISO14001:2015 environmental management system certification, ISO45001:2018 occupation health and safety management system certification. Dry-type transformers have also achieved France BV certificate, Norwegian DNV certificate, the United States ABS certificate and China classification society CCS certificate; and 31500kVA/35kV oil-immersed type transformer has passed CESI certificate; moreover, both oil-immersed type transformer and dry-type transformer have passed SIRIM certificate.
