Current transformer core

The stacking factor is ranging from 0.94 to 0.96. The magnetic properties of SB series cores are very close to that of A series cores, the Bm values are relatively lower because it is recycle material.

The appearance of the SB cores are very similar to traditional toroidal cores. Material thickness 0.20mm, 0.23mm, 0.27mm, 0.30mm and 0.35mm are available.

SB series toroidal cores are developed to satisfy the customers who are eager to minimize their cost, which are wound by a continous silicon steels strip, occasioinally with joints.

low cost and good perforance.
