Big Size Magnetic Materials Nanocrystalline Cor for Instrument Current Transformer

Instrument Transformer Core Design:

We design & produce Oval nanocrystalline ring core & instrument current transformer based on specifications & drawing, details including:

1. Bare core size, Size finished

2. Current Transformer Turns Ratio

3. Capacity (VA)

4. Accuracy
