Transformer core: 1. Close flux path 2. Low magnetic leakage and low noise 3. High efficiency 4. Light weight
Transformer 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: (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
