Abstract
A winding system for gas-cooled transformers, comprising windings disposed around a core; and at least one insulation torus, consisting of an insulating mass, said torus having embedded therein electrodes electrically connected to an adjoining winding for suppression of the electric field intensity between sinding and electrodes. The winding connected to the electrodes is divided into separate winding sections across the height of the winding, and each of these sections is connected to one electrode.
