A. the material of iron corn is high magnetic flux cold rolled grain oriented silicon steel sheet, of which the thickness
is less than 0.3 mm.Meanwhile, Protective resin covered on the surface of iron core for Moisture proof and rust proof.
B. The structure of low voltage winding is Cylindrical, which is made by copper foil. The high voltage winding has the structure
of Multi-storey. The style of designing can improve the mechanical strength and the ability of Anti short circuit.
C. The cooling system equips low noise fans adapted by Temperature Controller to add 40% more capacity for the Transformer.
D. the Protection Level of the transformer executed by the standard of IP20 can defense the transformer from any items
which the diameter is greater than 12 mm. To meet the needs of clients, the protection level can reach to IP23,
which can defense ≤60 degree angle water falls.
E. No load loss and load loss meet the standard of GB/T 10228-2008, however, the no load loss of SC(B) 10
is lower 10% of the standard of GB/T 10228-2008 and the load loss is lower than 5% of GB/T 10228-2008.
