DISTRIBUTION TRANSFORMER

3.3kV, 6.3kV, 6.6kV, 11kV (13.2kV/13.8kV/15kV/20kV/22kV/33kV/34.5kV) to 0.38kV, 0.4kV, 0.42kV, 0.44kV up to 25000kVA

With or without on-load-tap-charger type distribution transformer is made of high-quality silicon-steel sheets, and laminated by steps, it is advantageous in low loss, low noise, low voltage partial discharge and high anti-short circuit capacity.

The dynamical and thermal stability of this transformer, of which the coils are winded by high-quality oxygen-free copper wire as well as used pre-compressing brackets processes and interior and exterior structure.
