Abstract
The lightning arrestor has two metal end fittings for connection purposes, a stack of electrically conductive components extending along a longitudinal axis between the two end fittings, and an envelope surrounding the electrical components and the end fittings in such a manner as to maintain electrical contact between the components. The envelope is made of a thermoplastic material that molded over the electrical components and the end fittings. It has an embossed outside surface including depressions and projections. The depressions correspond to zones of reduced envelope wall thickness and they serve to constitute lateral openings through the envelope for allowing gas to escape to the atmosphere.
