To fix the conductors and coils of wind overhangs and to fill cavities in the winding overhangs of electrical machines, strings are used which include compressible rovings (1) made up of fibers and surrounded by an elastic sheath (2) which is permeable to impregnating resin. A spacing is introduced into the winding overhangs with a thickness which is greater than the spacings to be filled. The strings are impregnated after they are pulled in. To improve the overhang corona shielding, the strings are treated with a conductive impregnating agent which is permeable to the impregnating resin before they are pulled in.
