Wire wound transformers
Wire-Wound Transformers
Wire-wound transformers are widely used in low-voltage applications where compact dimensions, flexibility and relatively low power ratings are important.
At TRAFA, wire-wound transformers are primarily applied in single-phase applications up to approximately 10 kVA and three-phase applications up to approximately 15 kVA. Depending on the electrical specification, round wire, profile conductors and various core constructions can be used.
Designed Around the Application
Every transformer is designed based on the required voltage, frequency, operating environment and available installation space.
Available configurations include:
- Single-phase and three-phase transformers
- 50 Hz, 60 Hz and higher frequency applications
- Insulation class B, F or H
- Isolation transformers
- Control transformers
- Transformers with tapping points
- Designs with electrostatic screens
- Marine and industrial duty applications
EI and UI Core Constructions
Wire-wound transformers are typically built using EI or UI laminated cores. The final core selection depends on the electrical requirements, available space and desired performance characteristics.
By combining different core materials and construction methods, a suitable solution can be developed for a wide range of applications.
Compact and Versatile
Wire-wound transformers are commonly used in machinery, control panels, power distribution systems and industrial installations.
When power ratings, voltages or environmental conditions differ from standard solutions,
we are happy to evaluate which transformer design is technically the most suitable for your application.
