Dry Type vs Oil Immersed Power Transformers

How to Choose?

Choose Dry Type Transformers when fire safety, indoor installation, and environmental protection are priorities.

Choose Oil Immersed Transformers when higher capacity, outdoor installation, and cost efficiency are required.

Comparison Item	Dry Type Transformer	Oil Immersed Transformer
Cooling Method	Natural / forced air	Insulating oil
Fire Safety	Non-flammable	Requires oil fire protection
Environmental Impact	Oil-free, eco-friendly	Oil containment required
Installation Location	Indoor, load centers	Outdoor, substations
Maintenance	Very low	Periodic oil inspection
Capacity Range	Medium capacity	Medium to large capacity
Initial Cost	Higher	More cost-effective
Operating Cost	Low	Low over long-term operation

Power Transformer Selection Guide — Expert Answers

Q: How to calculate transformer capacity for a factory?

A: Total load (kW) × 1.25 safety factor ÷ power factor. Example: 500kW factory → 500×1.25÷0.8=781kVA → choose 800kVA.

Q: What is the typical lead time for a 2500kVA transformer?

A: 30-45 days for oil-immersed, 20-30 days for dry type. Rush order available (+15% cost, 2 weeks).
