Arya transformers offer varieties of transformers. Lt power transformers are core/shell type transformers with copper winding. These are air/oil cooled, with auto/double winding. These transformers are available in single and three phase versions, or three phase to single phase conversion type. Also available are power/high frequency type with leakage inductance and b/f class insulation. Rating for single phase is up to 100 kva and for three phase, up to 500 kva. Higher ratings are available on request. These transformers are used for ups and ac drives [frequency control], textile machines, servo stabilisers and many other functional areas.
