SZ10-31500/220 power transformer is a type 10 energy-saving series 220kV class on-load voltage regulating power transformer. Adopting advanced design concepts and manufacturing processes, the no-load loss is reduced by 15-20% compared with traditional products, and the load loss is reduced by 10-15%. The energy saving effect is remarkable.
Equipped with high-performance on-load tap-changer, it can realize voltage regulation under load to ensure stable power supply quality. The fuel tank adopts corrugated or chip radiator structure, which has excellent heat dissipation performance and adapts to different ambient temperature conditions.
It is suitable for 220 kV substations, large power plant delivery projects, regional power grid hubs and other occasions. This product complies with GB1094 series national standards and GB/T 6451-2015 “Technical Parameters and Requirements of Three-phase Oil-immersed Power Transformers”, and meets the national secondary energy efficiency standard.
