ABSTRACT:
An electrical device comprising a plurality of electrical assemblies formed as interchangeable modules, aligned in an end-to-end serial array and enclosed in a polymeric weathershed housing, the electrical assemblies being electrically and mechanically coupled together. Each electrical assembly in turn comprises a plurality of electrical components 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 nonconductive filament winding. The electrical components can be varistors, resistors, capacitors, and insulators or any combination thereof. In the case of varistors used to form a surge arrester, for example, voltage ratings can be enlarged merely by serially coupling a plurality of separately wrapped electrical components in the form of MOV blocks. Enclosing the electrical assemblies is a weathershed housing, which tightly receives the assemblies therein and which facilitates construction and allows the practice of good dielectric design.
