Product introduction
SZ11 Series on-load regulating Power TransformerOLTC,is applied CAD tools with advanced design,reasonable structure,excellent choice of materials,the indicators insline GB/T1094"power transformer"and GB/T6451 "three-phase oil-immersed power transformer parameters and requirements"and GB20050-2020 "power transformer limited value of energy efficiency and energy efficiency grade°,is currently the leading domestic level.Industry andagriculture can be widely used in urban and rural power grids,energy conservation and environmental protection are important.This product is laminated iron chips was stage-like manner,changed the traditional core laminated old process,the internal magnetic circuit to improve the distribution of the core,so that the load loss,no-load current and noise than conventional laminated core of the transformer means reduced by 20%,respectively,load loss decreased by 10%.
