Dry Type Transformers
Dry type transformers can be installed wherever oil filled units cannot be used such as inside buildings, in tunnels , cranes , off shore platforms, ground catchment areas, public places etc.
PRODUCT FEATURES
- High impulse & dynamic short circuit strength.
- Good overload capacity.
- Low partial discharges & Lower losses.
- Non-hygroscopic & fire resistant.
- Well suited for damp and/or contaminated areas.
- High Performance towards dealing with seismic phenomena.
- Low cost of installation & maintenance.
- Drastically reduced maintenance and cleaner looks because of absence of any insulating liquid.
- A life-cycle analysis would reveal the cost-effectiveness of Dry type transformers in the long run though these require higher initial cost.
- Easy handling and access to active parts for inspection.
- The Dry type transformers are designed for required BIL values and are tested for dynamic short circuit.
