Tongchuang precise current instrument transformer core which is made by self-produced 1K107 DI nanocrystalline strips has high Saturation magnetic induction, 1.25T Bs, high magnetic permeability, good product stability and can work under -55—130℃ for a long time by widely used in the current transformer for measuring instrument.

Characteristics of iron core:
. High magnetic permeability -- greatly improves the precision of instrument transformer and reduces ratio error
. Superior temperature stability -- works under -55--130 °C for a long time
. In the condition of same dimension and performance of magnetic core, iron core is lighter and cheaper than permalloy.

Product Application
