A plurality of hooks, which are of one-piece construction with a casing substantially enclosing a transformer or choke, are engaged by a suspension means which allows the casing, exclusive of the hooks, to be immersed in an impregnating agent. After impregnation, the casing and enclosed choke or transformer are removed from the impregnant and air dried. The hooks and suspension means are not immersed in the impregnating agent.
