Uses of Corrugated Transformers
- For Pre-fabricated Substations, for compact dimensions and small installation space. It can be installed very near to loads, ie. building, etc and it ensures trouble free operations without interruptions.
- Installations cost are negligible.
- For Industrial purpose with advantage of space saving and better reliable cooling.
