Beschreibung
Zusammenfassung:	An overvoltage protective device comprises an insulating housing accommodating thereinside at least one column of non-linear resistors and a dielectric bush, both of which are closely enveloped by thermally conductive dielectric bulk material being in contact with the inner surface of the insulating housing. The wall of the housing of the dielectric bush is provided with through openings blocked by a layer of dielectric material. The inner surface of the dielectric bush forms a gas vent channel arranged lengthwise with respect to the column of non-linear resistors.
