Oil Type Transformer
Sudhir Power’s oil type transformer offers perfect solution for any application. High efficiency & low cost transformer form part of our wide range. Our transformer is certified by Bureau of energy efficiency.
Voltage regulation is provided with winding tapings as per customers’ specifications generally at +/-5% of input voltage. As a standard, tap changing is effected by means of externally hand-operated ‘OFF-CIRCUIT’ tap changing switch. On Load Tap Changers (OLTC) with a variety of steps that provide optimum control.
Every transformer undergoes a series of tests throughout the manufacturing process, right from raw material stage. All routine tests are carried out at our works as per IS 1180, IEC 60076-11 and other international specifications. Type tests for impulse withstand and short circuit strength etc., have been conducted on representative ranging and voltage national test houses.
Dry Type Transformer
- Cast Resin Transformer
- Vacuum Pressure Impregnation (VPI)
A full range of dry-type transformers with primary voltages through 72.5 kV built according to all major standards including IS, IEC and ANSI Offered to minimize environmental contamination and fire hazard.
These transformers meet strict parameters with respect to electrical system demands and functioning in areas with extreme climate conditions.
The dry-type transformers are moisture-proof, suitable for operation in humid or heavily polluted environment. They are the ideal for operation in environment with humidity higher than 95 % as well as at temperatures down to -25 °C. There is less space and less civil work needed, no special safety features are required (fire detecon). They are maintenance free and extended life is due to low thermal and di-electric ageing Looking at these advantages customers are specifying dry-type transformers more frequently
