Summary:The invention relates to monolith lighting arrester with high tensile strength and without inside gas room, limiting over voltage especially on outdoor electrical networks which is made of flexible insulating material surrounding ZnO varistors (3). The essence of the invention lies in that the ZnO varistors (3) are ring-shaped and attached to an electrical insulating bar (2) so that metal discs (4) ensuring good electrical conductivity are between the ZnO varistors (3) and armatures (1) located on the ends of the electrical insulating bar (2) are made of metal. Parafoudre monolithique sans chambre à gaz interne, à forte résistance à la traction, limitant les surtensions surtout sur les installations électriques extérieures et fait d'un isolant flexible entourant des varistors au ZnO (3). Le principe de cette invention réside dans la forme annulaire des varistors au ZnO (3) et dans leur fixation à une barre isolante (2), de sorte que des disques métalliques (4) d'une bonne conductivité soit situés entre les varistors au ZnO (3), et des armatures (1) placées aux extrémités de la barre isolante (2) sont en métal.
