<p>The invention relates to a surge arrester (1) having a tube shaped housing (2) an end fitting (3) connected to an end of the housing a varistor block arranged in the housing (2) and a supporting element (4) arranged in the region of the end fitting (3). The supporting element (4) comprises a supporting ring (5) which is in contact with the housing (2) and which comprises a cone (6) and a clamping ring (7) which comprises a counter cone (8) that corresponds to the cone (6). The cone (6) is braced to the counter cone (8) in such a manner that the supporting ring (5) is pressed to the housing (2) in a non displaceable manner. The supporting element (4) can thus also be used after the installation of the varistor block and also be removed.</p> |
