Amorphous metal Transformers
“Kotsons” Amorphous metal transformers are manufactured in technical collaboration with Hitachi Met glass Inc., the only Producer of Amorphous Metal in the World. Kotsons has set up state of the art amorphous metal transformer manufacturing facility by importing the latest amorphous metal cores manufacturing equipment from M/S Bergers Machinenbau GMBH, Germany.
This plant has the latest equipment in India to produce energy efficient amorphous metal transformers. Quality of process is given overriding importance to the quantity. Cores are annealed under absolute inert atmosphere to get at most lower losses thereby enhancing the energy savings in comparison with the similar manufacturing facilities in this line in the world.
Advantages :
- Energy Efficient
- AMDT can reduce No Load losses by 80 % Since No load losses represent a major portion of the energy lost during Power distribution Hence reduce cost investment for power generation & translate into reduction in carbon di-oxide emissions created during power generation.
- Lower Temperature
- Slower ageing of insulation
- Higher overloading capability
- Longer Life
- Superior electrical performance under harmonics conditions
Description :
In order to achieve significant improvement in efficiency, amorphous metal is used to make transformer core. Amorphous metal exhibits a unique random molecular structure unlike rigid grain structure of silicon steel, which enables easy magnetization & demagnetization, thereby reducing hysteresis loss. Further processing of amorphous metal in very thin lamination (appropriate 1/10th of silicon steel lamination thickness) enable significant reduction in eddy current losses.
The Advantages of AMDT is not limited to reduction in losses alone. Since these losses are converted in to heat energy , cooling oil inside the transformer tank will be heated up and it will lead to emissions and significant fuel savings. AMDTs helps utilities reduce harmful emissions such as sulphur dioxide, Nitrogen Oxides and Carbon dioxide, the pollutants that cause acid rain & global warming.
