SGB (DGB) series three-phase (single-phase) dry-type, isolating, voltage transformer is a multi-coil (double coil and above) structure voltage transformer, the primary and secondary windings are insulated from each other. Its transformation ratios are of fixed and tapping type, which enable voltage bucking and boosting. It can also electrically isolate input and output windings from each other to avoid risks of simultaneous access to electrified body (or electrified metal parts due to insulation damage) and ground hazard. Besides, it also has certain inhibiting effect of various kinds of interference.

Introduction to Products Its core is made of quality cold-rolled silicon sheet and is of a full-miter non-puncture structure and its coil is made of quality oxygen-free copper. It is artistic in appearance and safe in running and is widely used in transmission and distribution of industrial and agriculturalist. Main Function And Features It adopts radiator oil tank of corrugated sheet type or expansion type. As it doesnâ??t need oil conservator, the height of transformer is reduced , and as the transformer oil doesnâ??t contact with air , the oil ageing is retarded, thus prolonging the service life of transformer. The no-load loss of Model S10-M is 20% lower than that of Model S9-M , and S11-M is 30% lower than S9-M. the transformers are high in reliability , advanced in performance and rational in economical indexes . The oil tank is diversified in types and looks artistic and elegant.

Transformers can be supplied on demand to run at two different primary voltages, the shift between these input voltages has two basic alternatives: with a primary tap changer which can be switched with no load and no applied voltage or by changing terminals under the cover. V- LOW VOLTAGE The secondary voltage under no load is allocated at 400V, 415V, 433V, though other voltages can be supplied on demand. When usage requires two voltages, transformers with two simultaneous voltages can be supplied. In this case the no-load voltages are set to 400V(230V),415V(240V),433V(230V).
