<PICT:1003184/C6-C7/1> An electrode arrangement for cathodic protection of immersed structures comprises an electrode 1, preferably made of cast iron containing silicon, having a central bore of which part is tapered, wherein the electrical supply cable 2 passes through the bore. The electrode may be secured to the supply cable without being cut by tapering elements such as rubber packings 7 and 8 wedged, and preferably glued or cemented, in the bore between the cable and electrode and on either side of two tapered half-casings 5a and 5b, e.g. of copper, which provide electrical connection between a part of the cable from which the insulation has been removed and the electrode. Specification 898,840 is referred to. |
