Product Summary

Our gap core is designed for inductors and energy metering applications where controlled magnetic saturation and low excitation current are required. The distributed air gaps allow higher energy storage and reduce core loss, making it ideal for power filters, reactors, and current transformers with high DC bias.

Key Selling Points

• Distributed Air Gap – Prevents core saturation, enabling stable inductance under high current.
• Low Excitation Current – Improves energy efficiency and metering accuracy.
• High Insulation Strength – Suitable for high voltage (0.66KV, 0.72KV) applications.
• Customizable Design – Gap size and core dimensions can be tailored to specific application requirements.
• Wide Temperature Range – Operates reliably from -40°C to +155°C.
