(6) Green epoxy coating [maximum working temperature 180ºC, thickness 0.20~0.50mm].
(7) Black epoxy paiting.
High quality CRGO steels with low iron-loss and high permeability in thickness of 0.23mm, 0.27mm and 0.3mm.
It is toroidal and wounded in the same direction of closed flux path, no magnetic leakage, so its magnetic performance is best. The coil winding is easy and high efficiency with Toroidal winding machine.
Toroidal core is widely used in 50Hz and 400Hz transformers, current transformers, reactors, chokes and other magnetic components of electronic equipment.
