Comparing Dry and Oil-Filled Transformers

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

There are more reasons to like dry transformers. They use less energy and work with smart tech. You follow safety rules and do not worry about oil leaks. You get steady power in busy places like offices and hospitals.

Experts say dry type transformers are a good choice for the future. You make a smart and easy investment for your next job.
