Schools & Public Facilities
Well suited for campuses, stations, hospitals, and public projects where safer indoor installation is important.
Data Rooms & Critical Loads
Used where power continuity and dependable indoor operation matter, including equipment rooms and sensitive load areas.
Dry Type Transformer Selection Guide
We lock in the key items early—pole transformer voltage, insulation level, taps, vector group, and accessories—so what arrives on site matches your drawings, not “closest available.”
Voltage & Capacity
Matched to your actual load and power system for safer, more stable operation.
Single or Three Phase
Chosen to suit your equipment type, installation setup, and application needs.
Insulation Class
Selected to match the working environment and safety level your project requires.
Enclosure Protection
Different enclosure options help the transformer fit indoor conditions more reliably.
Temperature Rise
Proper temperature rise design helps support stable daily operation and longer service life.
Copper or Aluminum
Choose the winding material based on budget, efficiency goals, and delivery expectations.
Advantages of Dry Type Transformer
Dry type transformers are valued for their higher fire safety, strong suitability for indoor and enclosed environments, and better fit for locations where oil-immersed transformers are not preferred. They are widely used in high-rise buildings, commercial centers, transport hubs, communication facilities, important public infrastructure, and selected industrial applications where safety, environmental conditions, and installation location all play an important role.
Stronger Fire Safety for High-Risk Installations
One of the main advantages of a dry type transformer is its suitability for environments with stricter fire protection requirements. In projects such as high-rise buildings, transport facilities, and public infrastructure, where fire safety carries greater operational importance, this type of transformer offers a more appropriate solution.
Better Suited to Dense Urban and Public Areas
Dry type transformers are often a better fit for installations located closer to end users and public activity zones, such as commercial centers, communication facilities, and important city infrastructure. In dense urban settings, they are generally more aligned with practical needs in safety, installation environment, and distribution layout.
More Suitable for Underground and Enclosed Spaces
In underground buildings, metro systems, and other enclosed environments, ventilation, evacuation planning, and fire control usually require closer attention. Dry type transformers are better suited to these conditions, which is why they are commonly selected for this kind of installation.
More Flexible Enclosure Options for Protection and Appearance
Dry type transformers offer greater flexibility in enclosure materials and protective design. This makes it easier to adapt the product to different project requirements while balancing protection performance, visual appearance, and packaged distribution system needs.

Dry Type Transformer FAQs
What is a Dry Type Transformer?
A Dry Type Transformer is a transformer that uses air and solid insulation materials instead of insulating oil for insulation and cooling. Its windings are not immersed in liquid dielectric.
What is the main difference between a Dry Type Transformer and an Oil-Immersed Transformer?
The main difference is the insulation and cooling medium.
A Dry Type Transformer uses solid insulation and air cooling, while an Oil-Immersed Transformer uses insulating oil for both insulation and heat dissipation.
Where are Dry Type Transformers commonly used?
They are commonly used in:
- commercial buildings
- hospitals
- schools
- airports
- data centers
- shopping malls
- office buildings
- industrial plants
- metro and rail systems
- indoor substations
- high-rise buildings
They are especially suitable where fire safety, environmental cleanliness, or indoor installation is important.
Can a Dry Type Transformer be installed indoors?
Yes. This is one of its biggest advantages.
Dry Type Transformers are widely used indoors because they are well suited for buildings where oil containment, fire separation, and environmental cleanliness are major concerns.
What are the main advantages of a Dry Type Transformer?
The main advantages are:
- no oil leakage risk
- good fire safety characteristics
- suitable for indoor installation
- cleaner operation
- reduced environmental concern
- simpler oil-free maintenance
- good suitability for public and commercial facilities
What should customers consider when selecting a Dry Type Transformer?
Key points include:
- rated power
- primary and secondary voltage
- frequency
- insulation class
- temperature rise limit
- cooling method
- installation location
- enclosure protection level
- ambient conditions
- harmonic content
- noise requirement
