For example: RFN - CT - 046036018020 indicates a = 18 mm, b, c = 46 mm, d = 36 mm = 20 mm iron-based nanocrystalline rectangular transformer magnetic core.

2. The performance characteristics

Mixer with high saturation magnetic induction intensity, magnetic core can work under the condition of close to magnetic saturation, wound less, can reduce the volume of transformer and reduce the cost;

Pieces of high permeability, low coercive force -- measurement error is small, high sensitivity;

Mixer low loss silicon steel, permalloy core ideal alternative materials;

Pieces of good temperature stability, can be in worker and 55 ℃ ~ 130 ℃ temperature range work for a long time.

3. The application field

Mixer electric current transformer is important when its primary has alternating current input, the second level according to the proportion of output current. Is mainly used in safety and efficiency of power plants and transformer substations of high voltage, large current measurement and relay protection, current transformer to measure and control circuit and the measurement of high voltage circuit safe ones. With traditional silicon steel core materials and permalloy, iron-based nanocrystalline alloy with high magnetic permeability, low loss of obvious advantages, is mainly used in epoxy sealing bushing current transformers, low voltage, medium voltage, high voltage switch equipment, and other power transmission and distribution system equipment.

Precision grade: 0.5, 0.5 S, 0.2, 0.2 S.

Rated voltage: 0.38, 0.5, 0.6, 1,3,6,10,20,35,66,110,220,330,500,750 and 1000 kv
