The utility model relates to a capacitive divider, which comprises a shielding ring and a base. Three supporting columns are vertically arranged at the lower part of the shielding ring and are connected to the base; the end surfaces of the three supporting columns are horizontally distributed in a triangle shape. The three vertical supporting columns are arranged at the lower part of the shielding ring at the upper end of the capacitive divider, and the end surfaces of the three supporting columns are horizontally distributed in a triangle shape, thereby meeting the triangle stable principle, increasing the stability of the whole capacitive divider, reducing adverse impact of weather and environmental factors on the capacitive divider, and eliminating potential safety hazard existing in the capacitive divider during normal working of workers. The capacitive divider has advantages of simple structure, convenient installation and low production cost.
