SGB11 transformer is what we usually say "half packet" transformer, SGB11 dry type transformer specifications according to the capacity is generally between 100 ~ 2500KVA, is the ring type iron core structure and the United States DuPont NOMEX insulation materials together with the H class insulation open type air self-cooling ring iron core dry type distribution transformer, known as the "energy-saving magic"!
SGB11 series transformers are all copper windings; The low pressure is foil winding; The high voltage is continuous cake winding, which is impregnated and baked by 2000 class "1160" solvent free paint in vacuum and positive pressure immersion equipment for many times. Technical indicators for the international leading, in the choice to buy, to understand the difference between SGB11 and SCB11 dry type transformer.

For example: SGB11-100KVA,UK=6%,D, YN-11 dry type transformer model meaning
S stands for three phase
G - dry
B means the coil is a foil
11 -- Performance level code
100KVA is rated for capacity of 100 kV ampere
UK =6% represents the short circuit impedance with a value of 6%
D, yn11: Connection group label
D - primary (high voltage) side three-phase winding triangle (△) type wiring;
Y-secondary (low voltage) side three-phase winding star (Y) type wiring;
N-secondary side three-phase winding star (Y) type wiring neutral point extraction;
11-11 point connection, meaning the voltage of the line with the same name on the low voltage side is 30° ahead of the voltage of the line with the same name on the high voltage side.
