Industrial, Substation & Distribution purpose manufacturing range up to 2MVA. 11KV, 22KV naturally air cooled. A dry type transformer has an iron core, vacuum pressure resin impregnated high voltage windings and low voltage windings. The Low voltage winding is constructed with conductors. Depend nomex insulating material includes and apparatus to secure the windings in place during a vaccum and pressure resin impregnation process. The result is a coil that exhibits high short circuit protection due to the tightly bond conductors comparable to completely resin encased molded transformers at a substantially reduced cost. Transformers at a substantially reduced cost.
