Abstract
An electrical assembly, such as an insulator or a surge arrester, having an elastomeric weathershed housing, a pair of end fittings, and a pair of sealing systems for coupling and sealing the interfaces between the end fittings and the ends of the weathershed housing. Each of the end fittings has a bore for receiving an end portion of the weathershed housing, and an annular flange extending inwardly from the bore for engaging and compressing the end portion of the weathershed housing inwardly to form a primary annular seal without crimping the end fitting against the weathershed housing. At least one locking ring is positioned between the end portion of the weathershed housing and the inner surface of the bore for forming a secondary annular seal. Additional sealing can also be provided by axially compressing the weathershed housing between the end fittings.
