Method of manufacturing a lightning arrester and a lightning arrester obtained by the method

摘要

A lightning arrester includes a stack of zinc oxide pellets (1) seated in counterbored recesses of intermediate tubular spacers (2) and two metal end fittings (3). This assembly is wrapped in a filament winding (4) at an angle of 80-90 degrees with the stack axis, thereby providing radial binding without significant axial compression. The filament winding adheres to the side surfaces of all the components of the stack.
