Voltage transformer divided by the number of phases: the vast majority of products are single-phase high-voltage transformer Langfang, Shijiazhuang because voltage transformer high voltage transformer capacity is small, the plot is not the body inside and outside the high-voltage transformer Hengshui, three-phase high voltage bushing between high voltage transformer insulation requirements difficult to meet, so only 3-15kV products sometimes using three-phase structure. Voltage transformer divided by the conditions of use: indoor voltage transformer: power distribution equipment installed in the room, generally used in voltage level and below; outdoor type voltage transformer: power distribution equipment installed outdoors, and is used in over voltage rating.
