Bushing insulator

摘要

A bushing insulator or other corresponding component, comprising an end-to-end primary current conductor (1) and a frame (2) cast of cast resin (3) around the primary current conductor. In accordance with the invention, the primary current conductor (1) comprises a fuse (4) which is at least partly left within the cast resin (3) when casting the frame (2). The part of the fuse (4) remaining within the cast resin (3) is encapsulated in a layer (6) of rubber or other corresponding material which in turn is encapsulated in a semiconducting layer (5). <IMAGE>
