Product introduction
SZ11 series on-load voltage regulator power transformer, using CAD means, advanced design, reasonable structure, excellent choice of materials, the indicators meet GB1094-2013 "power transformer" and GB/T6451-2015 "three-phase oil-immersed power transformer technical parameters And requirements "standards, at the current domestic leading level. It can be widely used in urban and rural industrial and agricultural power grids, and has important significance for energy conservation and environmental protection. The stacking mode of the product core chip is in a stage shape, which changes the traditional core stacking process and improves the magnetic circuit distribution inside the core, so that the no-load loss, no-load current and noise are more than the traditional type of stacking. The core transformer is reduced by 20% and load loss is reduced by 10%.
