- At least one of the power connectors should be a detachable one Connection, in particular a connector included. At least part of the Varistor columns can then be independent of the formation of the series circuit necessary power connectors very easy by mechanically connecting the Assembly units are manufactured. By closing the detachable connection can then realized the desired circuit after completion of the varistor columns become.
- the isolators provided in the multi-column active part during operation of the inventive arrester are exposed to large electrical loads, It is recommended that at least one of both pipe ends of the isolators To arrange field control electrode. On the one hand, this causes the insulator to act electric field evenly, on the other hand, this electrode serves at the same time also the centering of the adjacent in the varistor column varistor. With advantage the field control electrode has an annular bead. This bead serves to accommodate the pipe end and the centering of the insulator. Around To save additional parts, can be connected to the field control electrode one of Power connector to be molded.

- the loops 9 are made of a resistant to fission products of the insulating gas Material. Depending on the composition of the insulating gas, Are thereby placed on the material different requirements, which in an insulating gas based on nitrogen are much lower than in a Insulating material based on sulfur hexafluoride. Such material is an advantage Composite based on fiber-reinforced polymers.
- the fiber reinforcement is generally by wound threads based on glass or polymer, such as especially polyester, polyamide or polyimide, formed, but can also be otherwise structures incorporated into the polymer of the composite such as fabrics, tapes or mats included. To protect the fiber reinforcement is the composite coated with a cleavage product resistant protective varnish.

- Ableiter nach Anspruch 10, dadurch gekennzeichnet, dass die Isolatoren (18, 18') jeweils rohrförmig ausgebildet sind und eine in Richtung der Kapselungsachse ausgerichtete Rohrachse aufweisen.
- Ableiter nach einem der Ansprüche 10 oder 11, dadurch gekennzeichnet, dass mindestens einer der Stromverbinder (21, 21') eine lösbare Verbindung, insbesondere eine Steckverbindung (24), enthält.
- Ableiter nach einem der Ansprüche 11 oder 12, dadurch gekennzeichnet, dass an mindestens einem beider Rohrenden der Isolatoren (18, 18') jeweils eine Feldsteuerelektrode (22) angeordnet ist.
- Ableiter nach Anspruch 13, dadurch gekennzeichnet, dass die Feldsteuerelektrode (22) eine ringförmig ausgeführte Sicke (23) zur Aufnahme des Rohrendes und zur Zentrierung des Isolators (18, 18') aufweist.
- Ableiter nach einem der Ansprüche 13 oder 14, dadurch gekennzeichnet, dass an die Feldsteuerelektrode (22) einer der Stromverbinder (21) angeformt ist.
- Ableiter nach einem der Ansprüche 11 bis 15, dadurch gekennzeichnet, dass in die Rohrwand des Isolators (18) mindestens eine Entlüftungsöffnung (25) eingeformt ist.
