Transformer selection is one of the most critical decisions in electrical infrastructure projects. The location, load profile and safety requirements of your project directly determine whether an oil-type or a dry-type transformer is the right choice. At ÖZ GÖKÇE ELEKTRİK, we have been manufacturing both technologies since 1997, offering our customers the solution that best fits their needs.
Oil-Type Transformers
Oil-type transformers are the classic, proven technology in which windings and the core are cooled in mineral oil. With their high efficiency, long service life and outdoor durability, they are the standard choice for grid applications.
Advantages:
- Reliable operation under heavy load conditions thanks to high cooling capacity
- Hermetic or conservator-type design options suitable for outdoor installations
- Wide power range from 25 kVA up to 5,000 kVA
- Long service life thanks to a maintainable construction
Dry-Type Transformers
Dry-type transformers use air and resin insulation instead of oil. They are the solution that meets safety requirements in indoor locations where fire risk is critical — hospitals, shopping malls, hotels, metro stations and high-rise buildings.
Advantages:
- High fire safety as they contain no flammable oil
- Minimal maintenance requirements
- Compact design suitable for indoor installation
- Environmentally friendly: no risk of oil leakage
Key Selection Criteria
Installation site: Oil-type units stand out in outdoor and grid applications, while dry-type units are preferred in enclosed spaces with heavy human traffic.
Load profile: For continuous and heavy loads, the cooling performance of oil-type transformers provides an advantage.
Safety regulations: The fire regulations your project is subject to can directly influence the choice.
Total cost of ownership: Evaluate maintenance, losses and lifetime operating costs together with the initial investment.
The ÖZ GÖKÇE Difference
