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 0.05mmTransformer 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, 0.23mmMaterial GradeEquivalent GradeBm (Gauss)BIM3-0.23mm16500/17000BIIM4-0.27mm/0.30mm16000BIIIM5-0.30mm15500Can produce according to customers’ specification.Toroidal core application:Power transformerInductorInstrument transformerAudio transformerVoltage regulatorsBallastThe advantage of toroidal core (Compare with EI core)Smaller sizeLighter weightLess magnetic leakageBetter over-load capacityLow temperature riseEasier design and mount More informations,pls.connect our other products.
