Abstract

Embodiments herein provide a gas-insulated disconnector (300) for an electrical apparatus (200) that comprises a first contact (310) having a longitudinal center axis and a second contact (320). At least one of the first contact (310) and the second contact (320) is movable in a direction of the longitudinal center axis of the first contact (310), where the first contact (310) is connected to the second contact (320) in a closed position and disconnected from the second contact (320) in an open position. The second contact (320) comprises a pre-determined contact portion (325) that has a roughness higher than a roughness of neighbouring contact portions of the second contact (320), where the pre-determined contact portion (325) is closer to the longitudinal center axis of the first contact (310) than are said neighbouring contact portions.
