The utility model discloses a capacitor group formed by connecting multiple strings of sections, comprising a plurality of capacitor blocks which are connected by post insulators and are arranged vertically; the capacitor blocks are internally provided with a plurality of capacitors which are connected in a head-to-tail manner by connecting lines; the two sides of the capacitor blocks at the upper end and the lower end are provided with 20kV post insulators which are connected with the capacitors closest thereto; and the 20kV post insulators are also connected with porcelain bottles of the capacitors extending out of the capacitor blocks. For the capacitor group, the capacitors are connected in the capacitor blocks, and then capacitor blocks form the capacitor group; and the gap between the capacitors is enlarged, simultaneously, the occupied area is reduced, the noise is reduced, and the production and installation cost is saved.
