110kV three-phase on-load tap-changer interconnection transformer

SSZ20-50000/110-NX2
This product is a 110kV three-phase three-winding oil-immersed on-load tap-changer tie transformer, independently developed and designed by TBEA. It is one of the key equipment in 110kV voltage level power transmission and transformation projects, serving to connect power grids of different voltage levels and meet the needs of the power system by adjusting the output voltage.

Product Advantages
Adopting advanced simulation verification technology, it boasts strong short-circuit resistance.
Advanced magnetic flux leakage control measures are adopted to reduce load losses.
Adopting a mature design scheme, the product boasts stable performance.
It is safe and energy-efficient, with simple operation and maintenance.
Application Scenarios
This product can be applied to 110kV voltage level transmission and transformation lines, providing strong support for long-distance, cross-regional, and large-capacity energy transmission.
