Abstract (en)
[origin: EP0181959A1] 1. Overvoltage arrester, which consists of a tubular insulating housing (1), in the ends of which two electrodes (2, 3) are inserted in a gastight manner and on the inside wall of which a longitudinal, narrow, electrically conductive or semiconductive layer (7, 8) is located, one end of which is electrically conductively connected to one of the electrodes (2, 3), the electrodes (2, 3) exhibiting a spark gap (6) between end parts (4, 5) which enclose one another and delimit between themselves and the housing (1) a particular chamber (11) and the electrically conductively or semiconducting layer (7, 8) being applied to the inside wall of the housing (1) in such a manner that it consists of lines (7, 8) which are arranged at a distance from one another parallel to the axis of the housing (1), characterized in that at least one elongated slot (12) or at least one strip-shaped projection (13) is located in each case between the lines (7, 8) of electrically conductive or semiconducting material.
