Abstract

Parafoudre à gaz à enveloppe métallique. Ce parafoudre comporte une tige disposée dans l'axe d'une enveloppe métallique cylindrique, et il est caractérisé par le fait que la tige est reliée par une perle de verre à une bague portant une collerette radiale, la collerette étant soudée électriquement sur l'extrémité de l'enveloppe où pénètre la tige. Utilisable pour la protection des installations téléphoniques contre les surtensions.
