<p>Coupling for the rigid and stationary end-connection of graphite or carbon electrodes whose ends contain a sleeve tube with an internal threading into which is screwed a double-threaded connector or nipple pierced with holes acting as reservoirs containing a solid and electrically conductive cement, characterised in that at least one of the said reservoirs is filled with a synthetic cement consisting of a thermosetting resin, which, in the presence of a catalyst, melts at a temperature greater than 60 DEG C in order to form a liquid phase with a viscosity below 2500 centipoises between 90 DEG C and 120 DEG C and to polymerise at a temperature greater than or equal to 120 DEG C. <IMAGE></p> |
