Current lead-in of the coaxial type, including at least two conducting tubes passing through a container wall, a gas-tight seal disposed between the tubes and the walls, an induction heating coil supplied with high frequency current from the tubes for producing a melting zone in a semiconductor rod, and a pressure-deformable electrically-insulating tension element disposed between the tubes. The tubes are in the form of an inner end and an outer tube. A pressure plate and a ring are disposed near one end of the inner tube, a ceramic tube surrounds the inner tube between the ring and the tension elements, and a ceramic ring stop is disposed at the other end of the inner tube. The ceramic tube and tension element have smaller outside diameters than the ring and stop and they are surrounded by the outer tube. Pressure is applied to the tension element by screws in the pressure plate or by a nut screwed onto the inner tube.
