Therefore, the surge arrester can quickly and in a process that is particularly suitable for mass production getting produced.
  • Such a method is advantageously carried out as follows: In the already the lower armature 3 containing and therefore cup-shaped Isolierstoffrohr 5, the active part 8 is inserted and subsequently closed the upper end of the tube 2 by screwing the valve 6. To screw in can engage in the through holes 11 a tool. The valve 6 is screwed into the inside of the tube until the contact cam 12 of the two valves 5 and 6 rest with sufficient contact force on the two end faces of the active part 8. Since the tube 2 has a relatively high elasticity, it is ensured that this contact force is maintained during the operation of the surge arrester.
