<p>An electrical device (50) includes a plurality of electrical assemblies (52,54,56) formed as interchangeable modules, aligned in an end-to-end serial array and enclosed in a polymeric weathershed housing (58), the electrical assemblies (52,54,56) being electrically and mechanically coupled together. Each electrical assembly in turn has a plurality of electrical components (60,62) aligned in a row and in electrical connection with one another via their axially-directed ends and under an axially-directed compressive force via a non-conductive filament winding (64). A plastic film barrier (110) laterally surrounding the electrical components (60,62) is interposed between the electrical components (60,62) and the filament winding (64). A surge arrester with voltage ratings can be enlarged merely by serially coupling a plurality of separately wrapped electrical components (60,62) in the form of MOV blocks. Enclosing the electrical assemblies (52,54,56) is a weathershed housing (58).</p> |
