A METHOD AND PLANT (1) FOR THE INTRODUCTION OF A LIQUID INTO A MOLTEN MASS UNDER PRESSURE ARE DESCRIBED. SUCH A METHOD AND SUCH A PLANT (1) ARE PARTICULARLY BUT NOT EXCLUSIVELY SUITABLE FOR THE FORMATION OF A COATING LAYEY (5, 6, 7) ON A CABLE ELEMENT COMPRISING AT LEAST ONE CONDUCTOR (4), SAID LAYER (5, 6, 7) COMPRISING AN EXTRUDED THERMOPLASTIC POLYMER FORMING A CONTINUOUS PHASE INCORPORATING A DIELECTRIC LIQUID, AND ARE USEFUL, FOR EXAMPLE, IN THE PRODUCTION OF AN ELECTRIC CABLE (3) FOR THE TRANSPORTATION AND/OR DISTRIBUTION OF ELECTRICAL POWER.THE METHOD COMPRISES THE STEPS OF BRINGING THE LIQUID TO A PREDETERMINED PRESSURE GREATER THAN THE PRESSURE OF THE MOLTEN MASS; FEEDING THE LIQUID INTO A PLURALITY OF STORAGE TANKS (12); AND INJECTING THE LIQUID INTO THE MOLTEN MASS AT AN INJECTION PRESSURE EQUAL TO THE ABOVE-MENTIONED PREDETERMINED PRESSURE BY MEANS OF A PLURALITY ON INJECTORS (13) IN RESPECTIVE FLUID COMMUNICATION WITH THE PLURALITY OF STORAGE TANKS (12).ADVANTAGEOUSLY, THIS ALLOWS TO ACCOMPLISH A SUBSTANTIAL CONTINUITY OF DELIVERY OF THE LIQUID IN A TECHNOLOGICALLY SIMPLE WAY AND AT LOW COSTS, WHILE ENSURING A DISPERSION AS UNIFORM AS POSSIBLE OF THE LIQUID WITHIN THE MOLTEN MASS.FIGURE 1
