Oil Immersed Distribution & Power Transformers for Grids
Characteristics
- The transformer core is made of amorphous alloy band, no-load loss is 60% lower than that of S9 transformer and 25% lower than the stipulated value of JB/T10318.
- The transformer adopts Ddyn11 to reduce the effect of harmonic wave to power grid and improve power supply quality.
- The transformer adopts vacuum casting tank core, which greatly improves the reliability and stability.
- The transformer adopts vacuum oiling method, which fully eliminates the bubbles, forming into oil tank.
- According to years of practical experiences, our products adopt advanced technology, so the winding insulation and lightning impulse test's full-wave peak voltage is 25% higher than that of national standard, thus to make sure that the transformer can run safely and reliably.
