Optional treatments of finished core:

1Uncut, non-impregnated.

2Uncut, lightly impregnated with epoxy varnish.

3Cut, fully impregnated with epoxy resin.

4Multiple-cut, fully impregnated with epoxy resin.

5Assembled with plastic cases [PP, maximum working temperature 110, thickness 0.4~0.8mm].

6Green epoxy coating [maximum working temperature 180, thickness 0.20~0.50mm].

7Black epoxy painting.


Material:

High-quality CRGO steels with the characteristics of low iron-loss and high permeability in thickness of 0.05mm, 0.23mm, 0.27mm, and 0.3mm.


Characteristic:


It is toroidal and wound in the same direction of closed flux path. No magnetic flux leakage. It has the best magnetic performance. It is easy and high-efficiency for coil winding with the toroidal winding machine.


Application:

The toroidal core is widely used in 50Hz and 400Hz transformers, current transformers, reactors, chokes, and other magnetic components of electronic equipment.
