Dry Type Transformers
 Products Dry Type Transformers
|
| We provide high quality Dry Type Transformers from 25 KVA to 5000 KVA that are widely used in the high rise buildings, off shore platforms/ oil rings, hotels, power plants, steel plants, chemical plants and so on. Our Dry Type Power Transformers are perfect for the places where safety is utmost priority as they are resistant to fire. We are counted among the prime Dry Type Electrical Transformers Exporters based in India. Some of the salient features of the Dry Type Transformers are listed below:
- Fire resistant safe
- Lower losses that the same rating in oil
- High short circuit strength
- Good overload capacity
- Environment Friendly
- Low-cost office of installation and maintenance
- Compact 30%smaller than oil Filled Transformers
- Fast return on investment (Duet energy savings and installation costs)
Advantages of Dry Type Transformers
- Zero Maintenance : Say goodbye to oil filterations, Leaks, Oil Topping, Replacing Diaphragms, Servicing Accessories.
- Fire Safe : Only materials used are metals, Ceramics, Fibreglass and Resin make it highly resistant to fire. The combustible material is just 1% of the total Tansformer weight.
- Quick & Easy Installation/Removal : No need for assembling radiators, Conservator & Protect Radiators, Conservator & Protection/Monitoring accessories as none are required. Site installations are faster and cheaper.
- Energy Efficient : Total losses are less compared to their oil filled counterparts. Result-Reduced Energy bills!!
- Locatoin near Load Center : Can be located in workshop, basement, Teerrace or any floor. Hence costly LT cable length are reduced resulting in reduced Cable losses & better voltage regulation.
- Reduceed Civil Costs : No need for oil soak pit, fire barrier walls. Due to absence of oil, radiators, space required and weight are less.
- Higher Reliability : No more nuisance alarms and reduced trippings since all accessories required for oil monitoring & protection are eliminated in dry type transformers.
- Environment Friendly : No oil handling, spillages, leakages. Minimal non toxic smoke in case of a fire. Easily repairable even at site.
