Abstract: An insulator arrangement for an overhead line includes a suspension insulator for securing an overhead line to a tower and a line arrester arrangement which is disposed electrically parallel to the suspension insulator. The line arrester arrangement has a surge arrester, which is electrically connected to ground or earth potential, and a spark gap, which is connected to the surge arrester in series and which includes a first spark electrode connected to the overhead line and a second spark electrode connected to the surge arrester. The line arrester arrangement has an assembly or mounting insulator which can be secured to the overhead line. The first spark electrode is secured to a first securing device at a first end of the assembly or mounting insulator, and the second spark electrode is secured to a second securing device at a second end of the assembly or mounting insulator.

Abstract: An overvoltage arrester includes a column extending between first and second electrical terminals and having resistance elements being stacked on one another and having first and second opposite contact faces. The first and second contact faces of adjacent resistance elements adjoin one another. The column has a first group of resistance elements being directly connected by their first contact faces to the first electrical terminal and by their second contact faces to the second electrical terminal, and a second group of resistance elements being directly connected by their first contact faces to the second electrical terminal and by the second contact faces to the first electrical terminal. The result is a compact overvoltage arrester in which all of the resistance elements are connected electrically parallel with one another and which has a particularly high energy absorption capacity.
