Abstract
Abstract An electrical assembly comprising a plurality of electrical components aligned in a row under an axial load and wrapped with filament windings. The wrapped components are then preferably enclosed in a housing. MOV blocks can be used as the electrical components, resulting in a surge arrester having excellent heat transfer properties as well as improved tensile and cantilever strengths. The electrical components can be varistors, resistors, capacitors and insulators or any combination thereof.
