<p>The method involves using a meandering-shaped wire frame contained in a frame for fastening a central wall in grooved frames. The electrical current is fed by current conducting small electrodes in the form of banana plugs or metal spikes. The wire end areas vary in width and depth from the inside by various large holes for allowing the access to the current-carrying electrodes from the outside. The wire is located in the frame and used for constructing current-carrying electrodes which are guided through slots in the frame material.</p> |
