You might wonder how dry type transformers are different from oil-filled ones. The big difference is safety and how much care they need. Dry type transformers use air to cool down. Oil-filled transformers use oil, which can leak or catch fire.
Here is a quick look at the differences:
| Feature | Dry-Type Transformers | Oil-Filled Transformers |
|---|---|---|
| Cooling Medium | Uses air as the cooling medium | Uses oil as the cooling medium |
| Fire Hazard | Considered safer, used in public places | Considered a fire hazard, restricted to outdoor installations |
| Maintenance Frequency | Requires less frequent maintenance | Requires more frequent maintenance and oil sampling |
| Efficiency | Slightly less efficient, can overheat if overloaded | More efficient, better performance under load |
Dry type transformers lower fire risk by 95%. They also cut down environmental risk by 90%. If you need a transformer inside or in a city, dry type is usually best. Oil-filled transformers are better for outside or when you need more power for heavy work.
When you pick a dry type transformer, you get many good things. You save money and lower your risks. You also help the planet. Look at this table to see how they compare:
| Benefit Category | Oil-Filled Transformers | Dry Type Transformers |
|---|---|---|
| Fire Suppression System Cost | $25,000 | $0–$5,000 |
| Insurance Premium | Higher | Lower |
| Fire/Explosion Cleanup Cost | $100,000+ | Minimal |
| Risk of Oil Leak | High | None |
| Carbon Footprint | Higher | Lower |
