Our cast resin transformers are certified by ISO and CESI, an international certification authority. In 2008, we obtained the coveted seismic and vibration test (Q-Class) certificate, proving once more that our quality management and technical competence are unmatched.
Self-extinguishing characteristics of epoxy significantly reduces the spread and effect of a fire, and the possibility of explosion is nearly non-existent
Easy transportation and installation with simple structure
No toxic substance (oil or gas) discharged
Adopts a higher class epoxy resin
Epoxy Resin: uses H class epoxy resin, which is higher than the standard F class, as the main insulation material of the mold transformer to control thermal aging and extend the overall lifetime of the transformer by three-folds.
High stability and durability with strict quality management
Winding structure: when the radial build (RB) of the high-pressure winding is large, the temperature difference between the center and the surface of the winding gets higher, then crack in the winding may cause a partial discharge. Therefore, when the RB is large, an air duct is inserted making the RB thinner, then the temperature difference between the center and the surface is reduced and cracking is prevented.
When the air duct is inserted, the electric field distribution of the high-pressure winding becomes stable and the withstanding voltage becomes more resilient against external surge.
