NB Series toroidal cores

NB series toroidal cores are developed by Nicore to satisfy the customers who are eager to reduce their costs. The cores are wound of short silicon steel strips in 1 to 3 meters long. It is the particular feature of NB series cores to have joints in the flux path.

Dimensions:

Minimum strip width: 10mm

Maximun strip width:180mm

Minimum inside diameter: 20mm

Maximun outside diameter:450mm

Application

Toroidal cores are used in instrument transformers power transformers inductor transducers and variable transformers.
