Utilities & grid
Power transformers for utilities and industry.
Oil-immersed power transformers with CRGO cores, ONAN/ONAF cooling and optional OLTC with RTCC & AVR — designed to IEC, IS, ANSI or BS standards.

Built to your specification
Ambient temperature, top-oil and winding temperature rise, altitude, cooling and colour are all designed to the customer's specification. Insulating fluids include PCB-free mineral oil, Midel 7131, silicone oil and Nynas Nytro.
Designs up to 20 MVA, 33/11 kV have been type tested for temperature rise, lightning impulse and short-circuit withstand at CPRI (Bhopal) or ERDA (Vadodara). Manufacturing capability extends to 50 MVA, 132 kV.
For industry, too
The company serves utilities, manufacturing plants, oil refineries, textile mills and other medium to large industries with both power and distribution transformers, along with maintenance and testing services.
