Dry Type Transformer
‘Reliable’s make Air Cooled Transformer, Voltage ratio 11,22, 33/0.433KV, 3 Ph, 50 c/s A.C. at NO LOAD suitable for INDOOR installation, core type, double Copper wound, (AN) naturally self cooled type. The winding will be connected in Delta/Star as per vector group ref Dyn11. The Transformer will be designed and manufactured generally conforming to IS: 2026/77, IS: 11171/85. The Tapping of +5% to -5% in the step of 2.5% each on HT Side. will be
provided on PRIMARY side by means of an Off Load Tap Changer. The temp. rise of oil will not exceed 50 Degree Centigrade by thermometer method and that of winding 55 Degree Centigrade by resistance method over an ambient temp. of 50 Degree Centigrade. The class of insulation will be ‘A’. The transformer will be painted with Siemens Grey shade paint.
OFF Circuit Link Board
Transformer will be supplied with 5 Position Tap off Load Circuit Link Board from +10% to -15% in the step of 5% each on HT Side.
Type Of Insulation:
Imported insulation Nomex, Silicone varnish, Glass tapes etc. Coils are insulated with Nomex & glass tapes and vacuum pressure impregnated in Silicon varnish.
Core Material:
Imported cold rolled grain oriented, high permeability, and fully annealed Silicone steel with low loss, with full mitred joint construction.
Winding Material
EC Grade copper LV Winding – LV Windings are made of copper with nomex paper interlayers which are extremely rugged in construction and also capable of withstanding short circuit current situations as well as voltage surges more efficiently.
HV winding – HV Windings are made of EC Grade copper strips with Nomex covering (50:50 overlap) will be provided along with winding temperature alarm and trip protection.
Dry type Transformers has the following advantage:
- More efficient
- Non toxic
- Highly safe
- Non flammable
- Space saving by placing near the load end
- Low Noise
- Low Maintenance
- Can be supplied with off circuit link

The High-frequency noise can interface with digital Electronic Equipment Causing data corruption erratic behaviors, loss of memories etc
Isolation Transformers eliminate such noises and attenuates the spikes to minimal values, providing complete protection against such electrical disturbances. It consists of double wound Transformers with Extremely low coupling capacitance to isolate the voltage spikes and reduce noise from mains with extremely high insulation resistance. It is generally installed with the separate machines.
