Abstract (en)
[origin: EP0887810A1] The fitting for an electrical insulator of composite structure with a hollow shank consists of a metal body (2) e.g. of aluminium alloy with a cavity (3) forming a sleeve for the insulator shank. The cavity has a basically truncated conical inner wall (S), diverging towards its base and having an inward bulge, so that the gap between the cavity wall and cylindrical shank surface increased in a non-linear fashion towards the base. Prior to inserting the shank the metal housing is heated, and adhesive is applied to the end of the shank. On cooling to ambient temperature the shank becomes locked in place and the adhesive sets. In a variant the shank can be cooled with liquid nitrogen before insertion.
