ABSTRACT:
A surge arrester for providing overvoltage protection for communications lines and the like comprises a pair of electrodes having opposed faces to define the arc gap therebetween. The opposed faces include a pair of facing annular, concentric ridges, a valley opening radially inside of the annular ridges and an annular space or opening radially outside of the annular ridges. The valley opening and annular opening extend axially of the ridges to provide a maximum of relief or cavity space for particles that erupt from the electrodes during discharge regardless of the polarity of the electrodes. The cavity space is used for venting erupted particles away from the arc gap.
