Range of the Transformer

It differs from 250 KVA-5000 KVA (11 KV, 6.6 KV, 22 KV, 33 KV)

Core: The core employed is of the highest quality cold rolled grain attuned and laser advanced silicon steel sheet. They provide less noise, low iron loss, are crushed in extent and have the most outstanding performance for high efficiency transformers.

Windings: We use larger excellence conductor of aluminum or copper in our goods. These are rectangular or round aluminum or copper wires/ strips that are ridged with thermally better insulating paper are practical in oil engrossed modifiers. The winding has a flattened size, excellent heat transmission, high lighting impulse resistivity, low load loss, and excellent anti short-circuit power.

Insulation: Our oil submerged transformers are cloistered via electrical class insulated press board and thermally advance insulating Kraft paper.

Tappings: The Tappings series from + / - 5% in steps of 2.5% according to customer's needs.

Oil: The dehydrated out EHV Grade transformers oil according to the IS 355 (1993) with greatest recent alterations is used for suitable insulation and cooling following examination for all the restraints like resistivity, BDV, neutralization, tan delta, flash point and several more.

Bushings: The excellence porcelain bushings are taken into use on the low voltage terminals/ high voltage terminals. Elective bushing wells, elbows and inserts are accessible upon demand. High voltage cables are introduced straight and display no live portions outside.

The accessories contain of an oil drain valve, oil filling hole, regular thermometer, oil level gauge, safety valve, jacking pad, breather, skid wheel, earthling terminal

Optional Accessories
Buchholz relay, a cooling fan, cable duct, bus bar duct, HV and LV cable box, oil level gauge, OTI (Oil Temperature Indicator), dial-type thermometer, Marshling box, Pressure release valve, WTI (Winding temperature Indicator), lightening arresters and defensive fuse are available upon client's request at extra cost.


We provide above 33 KVA Transformers.
