Abstract
A surge arrester arrangement comprising includes a surge arrester (4) and a cut-out device (6) arranged in series with the arrester for automatic disconnection of the arrester in the event of arrester failure. The arrester arrangement is intended to be connected in parallel with an insulator (2) arranged for suspension of a power line (1) from a power line tower (3). The surge arrester (4) is connected to the power line (1) via a connecting link (5) in the form of a flexible electric conductor (10) enclosed in a tube of, for example, aluminium, which is divided into several parts, A helical spring (8) which, for example, may be arranged inside the tube, keeps the connecting link at insulation distance from the power line (1) when the arrester has become disconnected by means of the cut-out device (6).
