Abstract
The surge arrester contains a tubular encapsulation () of electrically conductive material that is filled with an insulating gas, an insulator () that is held on the encapsulation () and serves for supporting a current conductor (R) that is connected to a high voltage, an active part (R) that is arranged in the encapsulation () and comprises at least one varistor column () that is aligned along the encapsulation axis (A) and a field control element (). In order to maintain the manufacturing costs of this arrester at a low level, the field control element () and a first plug-type contact () of a plug connection () are held on the current conductor (R) of the insulator (), and a high-voltage electrode () of the varistor column () that is connected in an electrically conductive fashion to the current conductor (R) via the plug connection () contains the second plug-type contact () of the plug connection ().
