Magnetic Nanocrystalline Toroidal Core Current Transformer Coil For Instrumentation And Control

Instrument Transformer Core Design:

We design & produce 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

Key Material Properties:

• Higher permeability for higher measuring accuracy (when compared with silicon steel core)
• Excellent to replacement of Mu-metal
• High Bs, 1.2T
• lower manufacturing costs (when compared with permalloy)
• Long durability range  -30°C ~ + 180°C
