ABSTRACT:
A surge arrester has a gas-filled housing, in which, by means of a tubular insulating body, copper electrodes are positioned opposite one another in a spaced relation, and have a stepped, truncated conical shape. The electrodes, in the region of the active surfaces thereof, are designed with thicker walls than the conical sides in the region of the connection to the insulating body. The surge arrester is characterized in the case of small dimensions by good alternating current loading, surge current loading and life-span characteristics, combined with low response surge voltage and high extinguishing potential. The active surfaces of the copper electrodes are provided with a deep waffeling or honeycombing, or concentric rings, in which an electrode activating substance is anchored, the substance comprising aluminum powder and magnesium oxide. The surge arrester is particularly suitable for protecting communication lines.
