SZ11 series 10kV, 35kV three-phase on-load tap changer transformer
Classification:
Keywords: dry-type transformer series | oil-immersed power transformer series | special transformer series | box-type transformer series
Immediate ConsultationProduct Introduction
The SZ11 series on-load tap-changing power transformer, designed using CAD software, features advanced design, reasonable structure, and high-quality materials. All indicators meet the standards of GB1094/1996 "Power Transformers" and GB/T6451/1999 "Technical Parameters and Requirements for Three-phase Oil-immersed Power Transformers", placing it at a leading level in the domestic market. It can be widely used in urban and rural industrial and agricultural power grids, which is significant for energy conservation and environmental protection. The core stacking method of this product is staged, changing the traditional core stacking process, improving the magnetic circuit distribution inside the core, thus reducing no-load loss, no-load current, and noise by 20% compared to traditional stacked core transformers, and load loss by 10%.
