 toroidal transformer nanocrystalline core  

  

Transformer core / Toroidal core:  (A series)

A round core wound by automatic machines with one continuous tape of CRGO silicon steel and annealed in a tunnel furnace under the protection of inert gases.

Material thickness: 0.30mm,  0.27mm,  0.23mm, 0.10mm,  0.08mm and 0.05mm

 

Transformer core / Toroidal core: (B series)

 B round core wound by short silicon steel strips in 1 to 3 meters long, wounded with joints. They were annealed in vacuum furnace or tunnel furnace under protection of inert gases. The core posses the same advantages of A series, but the price was around 50-70% less than A series.

B series core commonly used as a replacement of EI and other toroidal transformers with lower magnetic loss requirement.

Material thickness: 0.30mm, 0.27mm, 0.23mm

 

Material Grade	Equivalent Grade	Bm (Gauss)
BI	M3-0.23mm	16500/17000
BII	M4-0.27mm/0.30mm	16000
BIII	M5-0.30mm	15500

Can produce according to customers’ specification.

 

Toroidal core application:

Power transformer

Inductor

Instrument transformer

Audio transformer

Voltage regulators

Ballast

The advantage of toroidal core (Compare with EI core)

1. Smaller size
2. Lighter weight
3. Less magnetic leakage
4. Better over-load capacity
5. Low temperature rise
6. Easier design and mount
