Tongchuang’s high-power 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. At the same time, the outside of our iron cores are packed in plastic box and stainless steel box with adhesive to protect magnetic core (as shown in the following figure)

Characteristics of iron core:
: . High magnetic permeability -- reduces the measuring error of current transformer
. High Saturation magnetic induction -- smaller and lighter than current transformer of silicon-steel sheet
. 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

. Measurement of transformer substation and protection of current transformer core
. Precise current transformers with 0.2, 0.2s and 0.1 precision level
. Low-voltage, medium-voltage and high-voltage switchgear
. Power transmission and power distribution equipment

*can be prepared according to the specifications and performances required by customers
