Dry Type Transformers
Emmess Manufactures DryType Cast Resin Transformers , casted coils are well known for their extremely low levels of Partial discharge.
Application
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.
- Emmess successfully conducted Seismic Qualification test on Cast resin transformers supplied to Nuclear Power Installations in India, way back in 1994.
