Abstract
The invention is directed to the provision of an external shield about the periphery of the housing of a surge arrester containing one or more arrester devices to provide an expansion limiting device which permits the housing to expand to a degree necessary to permit the expulsion of arc-generated gases within the housing while serving to help to limit the total expansion to a level below the elastic limit of the housing to prevent its destruction and permit its recovery after the gases have been dissipated. The shield may be made of metal, elastomeric materials, reinforced elastomeric materials or plastic, and the shield may be supported about the housing by an external strap of metal, plastic or elastomeric materials or may be supported by a plurality of fins arranged along the periphery of the housing and engaging an edge of the shield on its internal surface.
