| 摘要 |
The present invention relates to a method of manufacturing a lightening arrester, comprising the steps which consist in producing, on a stack of varistors (100), a first at least semi-rigid casing (300), having a constant external cross-section over its length, particularly compensating for the surface inequalities in the stack of varistors due to alignment offsets and to dimensional dispersions of the varistors, extruding an external casing (400) of substantially constant thickness over the first casing (300), then attaching annular fins onto the extruded outer casing. <IMAGE> |
