Abstract
An arrester has a plurality of laminated columns arranged in parallel, each having a plurality of nonlinear conduction elements. The columns are electrically interconnected by conductive connection members so that a conduction path is defined by the conduction elements and the connection members. The columns are arranged around, and in contact with, an insulating support column, which provides mechanical strength for the arrester. A plurality of such arresters may be arranged in an array, the arresters being interconnected by further insulating support columns. The laminated columns also contain insulating spacers and the spacers of two or more laminated columns may be rigidly interconnected. The arresters may be mounted in a casing filled with an insulating gas.
