Electrical assembly with insulating collar for coupling sections of

Abstract

An electrical assembly, such as an insulator or a surge arrester, utilizing a plurality of elastomeric weathershed housings for enclosing a core member therein. The elastomeric weathershed housings are coupled and sealed together by an insulating collar. A radially directed force is applied to the collar or the weathershed housings to cause intimate contact between the collar and the end portions of the weathershed housings to provide a weathertight seal. In the preferred embodiment, the radially directed force is provided by insertion of the core member into the axial bore of the weathershed housings causing radial outward expansion of the weathershed housings into intimate contact with the insulating collar. In another embodiment, the radially directed force is provided by a heat shrinkable insulating collar, which is shrunk about the end portions of adjacent weathershed housings. The core member can be an insulating rod or a plurality of electrical components, such as metal oxide varistors.
