GOSS E-Cores
Grain-oriented silicon steel E-cores providing traditional laminated core design with reliable magnetic performance and easy pre-wound coil assembly for 50/60 Hz power transformers and inductors.
Custom GOSS E-Cores (Silicon Steel E-Cores)
Bridgeport Magnetics supplies reliable GOSS E-cores for power transformers and inductors. Our grain-oriented silicon steel E-cores offer a traditional laminated core design with excellent magnetic performance and easy assembly using pre-wound coils.
From standard sizes to custom configurations for industrial, utility, renewable energy, and other 50/60 Hz applications.
Why Choose GOSS E-Cores for Power Transformers and Inductors
Grain-oriented silicon steel (GOSS) E-cores deliver reliable magnetic performance with a traditional laminated design. This construction provides easy pre-wound coil assembly and consistent performance, making them a proven choice over non-oriented or less optimized cores in 50/60 Hz applications.
For engineers and manufacturers, this translates to:
- Simple and fast assembly using pre-wound coils
- Reliable magnetic performance at standard power frequencies
- Cost-effective solution for a wide range of transformer and inductor designs
- Excellent scalability for custom industrial and utility projects
