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.

A spark gap arrangement is disclosed. In an embodiment the spark gap arrangement includes a hollow body including an insulating material, the hollow body encompassing the main axis of the spark gap and two electrodes arranged on face-side regions of the hollow body so that a discharge space is defined in an interior of a chamber of the hollow body, wherein an inner wall of the hollow body comprises a depression so that the chamber projects radially outwardly over the inner wall of the hollow body on at least one face side.

Spark gap arrangement

A spark gap arrangement includes a discharge chamber, an electrode head and a contact connection arranged outside the discharge chamber. The electrode head is electrically conductively connected and mechanically coupled to the contact connection in such a way that, when the contact connection is removed from its position or when the contact connection reaches a preset position, the electrically conductive connection is interrupted, and the electrode head is mechanically decoupled from the contact connection so that the electrode head is movable in the direction of the discharge chamber interior and/or within the discharge chamber.
