Vijai has been producing DryType Cast Resin Transformers for more than 15 years. Vijai’s cast coils are well known for their extremely low levels of Partial discharge.
In service in diverse industries, Electricity Boards, Nuclear / Thermal / Hydel Power Plants, Railway Traction and high-rise buildings, hospitals, subways, underground vaults, tunnels, school, steel factories, chemical plants, etc. where safety is of prime concern.
- Precise casting under vacuum ensures extremely low levels of Partial discharge.
- Coils have smooth finish and are robust in construction.
- Vijai successfully conducted Seismic Qualification test on Cast resin transformers supplied to Nuclear Power Installations in India, way back in 1994.
