Abstract
To achieve a contact with copper electrodes that discharges axially to a slight degree and is especially favorable from a manufacturing standpoint, a gas-filled lightning arrester with a ceramic insulator and copper electrodes is provided having a contact ring which is soldered endwise on an edge of each bowl-shaped copper electrode. The height (h) of the ring is greater than the thickness (D) of the edge of the copper electrode. The contact ring is made of iron or a magnetic, stainless alloy with a coefficient of thermal expansion .alpha.=120'10.sup.'7 /.degree.C.
