Beschreibung
Zusammenfassung:	A gas-filled surge arrester includes at least two electrodes, a hydrogen-containing gas filling and an activating compound applied to at least one of the electrodes. In order to ensure the required operating behavior of the surge arrester even at temperatures to 40%, the activating compound contains nickel powder in an amount of 30 to 35% by weight and potassium silicate in an amount of 25 to 30% by weight as basic components, sodium bromide in an amount of 15 to 20% by weight, as well as aluminum powder, sodium silicate and barium titanate as further components each in an amount of 5 to 10% by weight.
