Characteristics
● The transformer core is made of amorphous alloy band, no-load loss is 80% lower than that of S9 typetransformer and 25% lower than the stipulated value of JB/T10318.
● Transformer adopts copper foil LV winding to strengthen the bearing capability against short-circuit.
● The transformer connecting group adopts Dyn11 to reduce the effect of harmonic wave to power grid. andimprove power supply quality.
● Full sealed structure, the oil tank is welded to tank cover tightly, prolong the service life, maintenance-free.
● The transformer adopts vacuum oiling mode, which fully eliminate blisters from winding, and guarantees stableinsulation.
● Before leaving the factory, each piece of transformer has been experienced full wave lightning impulse test thatthe peak voltage is 25% higher than that of national standard, thus to make sure that the transformer can runsafely and reliably.
