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.
