110kV SZ20 Series Double-winding On-load Tap-changing Transformer (Level 2 Energy Efficiency)

This product is equipped with advanced on-load tap-changing technology, capable of automatically adjusting the output voltage based on real-time dynamic changes in load current, ensuring consistently stable power supply voltage. It perfectly meets the high power stability requirements of applications such as industrial production and telecommunication systems. The core components are made with superior materials and craftsmanship: the iron core uses high-permeability grain-oriented cold-rolled silicon steel sheets with a 45° fully mitered joint process, reducing no-load current and losses while improving energy efficiency; the conductors are made of high-tensile-strength paper-insulated or enameled copper wire, ensuring reliable electrical connections; the windings are constructed in a layer or pancake structure, providing strong short-circuit resistance and enhancing operational stability and safety.
