A method for manufacturing of an electrode of a surge arrester, an electrode and a surge arrester are disclosed. In an embodiment, the method includes positioning an electrode body in an electrochemical cell with and an electrolyte solution for a nickel deposition. The electrolyte solution includes at least one or more of magnesium sulphate, sodium sulphate and sodium chloride and electrolytically coating the electrode body with a coating to form the electrode for the surge arrester. The coating has nickel and the electrolyte solution is configured such that a surface of the coating includes a reduced wettability.

Method of manufacturing an electrode for a surge arrester, electrode and surge arrester

A multi-step tube () of a ceramic material comprises a tube body () of the ceramic material having an inner wall () located inside the tube body (). A surface of the inner wall () is formed with a plurality of steps (). The steps () are formed to extend differently far inside the tube (). A multi-layered gas discharge tube comprises the multi-step tube (). An inner electrode () is disposed on a step (), and an outer electrode () is disposed on an outer surface () of the tube body (). A disc () is partially placed on a step () and the inner electrode () between the inner electrode () and the outer electrode () so that, in case of an electrostatic discharge, the discharge will only take place in the center of the multi-step tube () and not at the border of the isolated ceramic disc ().
