The present invention provides a capacitive voltage transformer, including: a capacitive voltage-dividing component and an electromagnetic unit. The capacitive voltage-dividing component comprises: one or more levels of stacks, and each stack is a coupling capacitor. The coupling capacitor includes: an upper cover plate, a lower cover plate, an insulating sleeve, a capacitor core, squirrel cage electrodes, volume matching devices, a high voltage lead, and a low voltage lead. The lowermost coupling capacitor is provided with a medium voltage lead and a lead terminal. The low voltage lead of the lowermost coupling capacitor is led out through a low-voltage leading-out tube arranged in the lead terminal, and the medium voltage lead of the lowermost coupling capacitor is led out through a medium-voltage leading-out post arranged in the lead terminal. The medium-voltage leading-out post passes through and out of the low-voltage leading-out tube and is arranged coaxially with the low-voltage leading-out tube.
