1.Product Feature
The sz9 on-load tap-changer power transformer is widely applies to urban and rural electric network construetion. The iron core is in ladder shape and changes the traditional piling way of iron core as well as the inner distribution of magnetic way. It also decrease the no-load consurmption, no-load current consurmption and noise pollution all by 20%. The new product applies CAD tool and marked with advanced design, reasonable structure, high quality material. It accords with GB1094-1996 and GB/T64511999.
