Abstract
The component with fault arc protection has an insulator in the form of a pillar, a first electrical conductor system which is provided on the insulator head and can be connected to high-voltage potential, and a second electrical conductor system which is provided on the insulator foot and can be connected to a ground potential. Each of the two electrical conductor systems contains an arcing electrode (7) for dissipating any fault arc which occurs in the event of a discharge between the two electrical conductor systems. The fault arc is dissipated particularly effectively if at least one of the two arcing electrodes (7) is in the form of a cup and has a cup base (12), which is attached to one electrical connection of the first or of the second electrical conductor system, as well as a cup wall (13) which is adjacent to the cup base (12) and extends predominantly in the direction of the axis (2) of the pillar. In this case, at least two material recesses are formed, which extend from the cup base (12) to the cup rim (9, 10) and are predominantly in the circumferential direction in the cup wall (13).
