have adopted series of important reforms on the 110kV level three-phase oil-immersed on-loadtap changing transformer referring material, process and structure. The transformer has the features of small size, light weight, high efficiency, low loss, low noise, reliable operation etc. which can reduce a large amount of power network loss and operation expense with significant economic benefits. It is suitable for power plant, substation, heavy section plant or enterprises etc.
