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.
Dupond nomex insulating material includes an apparatus to secure the
windings in place during a vacuum 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. |
