  4. Überspannungsableiter nach Anspruch 1, dadurch gekennzeichnet, dass der Fehlerindikator (6) aus Wachs hergestellt ist.
  5. Überspannungsableiter nach Anspruch 4, dadurch gekennzeichnet, dass der Fehlerindikator (6) aus Polypropylen-Wachs hergestellt ist.
  6. Überspannungsableiter nach Anspruch 4, dadurch gekennzeichnet, dass der Fehlerindikator (6) aus Polyäthylen-Wachs hergestellt ist.
  7. Überspannungsableiter nach Anspruch 4, dadurch gekennzeichnet, dass der Fehlerindikator (6) aus einem Wachsgemisch hergestellt ist, dessen Schmelztemperatur zwischen 100° C und 160° C beträgt.
  8. Überspannungsableiter nach Anspruch 4, dadurch gekennzeichnet, dass der Fehlerindikator (6) aus mikronisiertem Wachs hergestellt ist.
  9. Überspannungsableiter nach Anspruch 4, dadurch gekennzeichnet, dass der Fehlerindikator (6) aus gefärbtem Wachs hergestellt ist.
  10. Überspannungsableiter nach Anspruch 1, dadurch gekennzeichnet, dass der Fehlerindikator (6) aus zwei miteinander verbundenen Schichten besteht, einer inneren (7), die mit dem Erdungsanschluss (2) verbunden ist, und einer äußeren Schicht (8).
  11. Überspannungsableiter nach Anspruch 10, dadurch gekennzeichnet, dass sich die beiden Schichten in ihrer chemischen Zusammensetzung unterscheiden.
  12. Überspannungsableiter nach Anspruch 10, dadurch gekennzeichnet, dass die innere Schicht (7) einen Farbstoff enthält.
