Abstract
A wound capacitor end connection is constructed by spraying a first layer of metal onto one end of a capacitor winding, positioning strands of a stranded conductor adjacent to the first layer, without mechanically securing the strands to the first layer, and spraying a second layer of metal over the strands and first layer to mechanically and electrically connect the strands to the first layer. In an alternative embodiment, the stranded conductor may be replaced by a perforated conductor having openings which provide additional electrical and mechanical connection points between the two sprayed metal layers.
